Terrible first marathon - seeking redemption

I run a 1:48 HM and had been training for a sub 4 marathon, 12 week block averaging 55km per week peaking at 70km. Longest three runs at 34, 32 and 30km. Did all my training with a goal marathon pace of 5:25 to be extra extra safe. Tapered fine, some hip issues but nothing major.

Where I think I failed: carb loading and sleep. I had an early flight to Gold Coast the day before the marathon and didn't get much sleep. Had an afternoon nap and thus couldn't sleep that night either. Final day of carb loading didn't go well; looking back think I may have gotten only 200g of carbs all day.

Woke up on race morning with some tummy trouble, but then I sat on the toilet for 30 minutes with no results so I'm unsure if it was just nerves. Thought I left early enough to get a warm up at the race start zone but the 5km journey took an hour due to packed trams. It was so packed that the moment you left the tram stop to walk to the start zone it was shoulder to shoulder and I couldn't get in a warm up.

Race started and right from the get go nothing felt right. My legs were heavy, as if I'd just done a 30km the day before. Stuck to a 5:40 pace and by the time the 21km mark came around my legs were screaming out in pain, I knew I couldn't maintain 5:40 for another 21kms and I didnt want to walk so I started slowing down. Didn't work. By the time I hit 33km I was plodding along at 6:30 and decided to walk/run the final 8kms. Final time 4:29 average pace of 6:23. I had 7 gels and 3 salt capsules.

I'm still trying to figure out what went wrong. Sometimes I go on my long runs on little sleep and it's fine. My phantom tummy trouble went on throughout the day, could it have affected my overall fatigue? Id spent 12 weeks and it blew up at the end.

Now I'm planning to run another marathon at my local route. But I'm unsure as to how much time I should wait until the attempt. I'll take a week off for my legs to heal then do a mini 3 week block and 1 week taper and try again. Is this unwise? I don't want to wait until next year 😭

First Marathon

Completed my first marathon. Elevation and terrain was tough, but best feeling to be able to finish!

u/wewenaar — 5 hours ago

My first half marathon. Crazy experience.How much does 268m of elevation gain usually affect a half marathon time compared to a flat course?

This was my very first official half marathon! Previously in training, I had only done a few long runs up to 17k–20k, but I always ran them completely "dry" with zero carbs.

​Today, I finally listened to the advice to fuel properly, packed a bunch of Tesco gummies, and just went for it.

​My stats today:

​Distance: 21.09 km

​Time: 2:02:26

​Average Pace: 5:48/km

​The course was way hillier than I expected, and hitting a massive incline at Km 3 forced me to slow down to a 6:29/km early on.

However, ​I ended up finishing with an insane negative split that I didn't even know I was capable of: 5:28 (Km 19), 5:14 (Km 20), and 5:12 (Km 21), passing a ton of people who were hitting the wall.

​I’m so incredibly proud of this first race, but I'm dying to know from the experienced runners here: how much did those hills hold back my clock?

Feet ache like crazy on long runs.

Hi all. I’m training for a marathon in October, although I have been running for a very long time and this is a relatively new issue for me.

During my long runs, my feet have been super achey. Not sharp pain, not cramps … just… achey. Every other part of my body has been fine.

Last weekend I did some research which led me to believe that maybe the nylon plate in my Endorphin Speed 4s were the culprit. So for today’s long run I used my Altra Flow Experience 3. My feet got so achey that at mile 6 (out of 11 total) I stopped at home and changed my shoes to my ES4 again. Didn’t really help. I have New Balance Balos as well, which are a much more “cushy” shoe, but I am light (105 lbs) and I don’t compress the foam well enough while running which leads to ankle issues. Can’t win.

Just wondering if anyone else has had an experience like this and I’m open to any suggestions. I have been doing foot stretches and strengthening exercises but I only started that routine a couple of weeks ago. I’ve also been icing my feet and rolling them out. Thanks for any advice you can offer!

Update: I changed my marathon training plan

Just over a month ago, I asked this community whether my marathon training plan looked okay. It was a plan to prepare me for a marathon in mid-October. Because of family commitments, it was built around three runs per week, and my goal time was 3:15.

I received a lot of valuable feedback. The main point was that my weekly mileage was probably too low, and many of you suggested I read up on some of the well-known marathon training plans.

So that's exactly what I did. I spent time learning more about marathon training, increased my mileage, and even bought a good second-hand treadmill so I can do my easy runs while my wife is out doing her sport.

Missed one weekend long run along the way. Last week I ran five times for a total of 62.5 km (39miles), and it felt great! Will do 4-5 runs from now on. The plan is to gradually build up to a peak of around 85 km (53 miles) in September.

I just wanted to say thank you to everyone who took the time to give me feedback. It really opened my eyes, and I'm now more motivated than ever.

Hopefully I'll have a successful marathon report to share with you in October.

Handheld (16oz/500ml) + Tailwind = Recipe for Disaster?

OK, so I'm way into my head right now and probably overthinking...also, huge caveat that nutrition is very individualized and different bodies react differently, sweat differently, have different needs...but generally speaking, my question is: Will relying on Tailwind mixed a little "heavy"/more concentrated throughout a ~4hour marathon set me up for disaster?

Longer version of the question...for training for and racing a full marathon am I risking disaster using just Tailwind for my carbs/salt/electrolytes when mixed with 16oz (500ml) water? The label calls for 20-24oz (590-710ml) water with each serving?

I'm targeting a 3:45 marathon. My thinking is aiming for 16oz (with full serving of Tailwind) every 5'ish miles.

This would give me:

  • 67g carbs/hour (on the 'low' end of what's generally recommended) -
  • 250g cabs for the whole race
  • 80oz water for the whole race

Considerations:

  • I'll probably want to supplement a source of carbs beyond Tailwind...candy, etc...here and there to get myself closer to 75g carbs/hour...seems doable?

QUESTION: How much am I running the risk of issues with hydration using the combo of Tailwind mixed with 16oz/500ml water? I know as you add carbs/sugar, it decreases how well the stomach is able to pull in water, right? The easiest solution to this is to sip plain water here and there at aid stations on occasion and during my training runs, right?

I know most folks run/train with gels, but I've taken to the ability to take in carbs steadily throughout my run as opposed to every _____ minutes taking a gel. I've tried a few different types of gels over the years but this route just seems better/preferable to me.

I absolutely plan on testing this concentration level, etc during training over the next few months but I was hoping to hear from folks who have run this road before to gain any insight or wisdom.

Thanks!

A personal anecdote illustrating how weather and weight impact running performance

Hi folks,

Background: I'm a 28-year-old recreational endurance runner (177 cm, 200-205maxHR) with 3 years of long distance running and 6 years of strength training. My PRs include 3:44 marathon, 1:37 half marathon, 44-minute 10K, and ~21-minute 5K and I have averaged 50k weeks pretty much for the last 2 years. After missing my January 2026 goal marathon due to food poisoning despite completing the 5min/km MP race target with Pfitzinger 12/55 plan successfully, I trained with Pfitzinger 12/70 for a May 2026 marathon targeting 3:10–3:30. The race ended far below expectations due to a combination of extreme weather, difficult training conditions, and unrelated psychological factors. This post focuses specifically on the physical and environmental reasons behind that performance.

  1. I didn't take the KK race conditions seriously enough. I had no idea how different a coastal city's weather is from where I live. In the images, I have compared some of my slow runs from race week to a 20-mile run today (5th July 2026, all times are in local time zone). My easy pace is 5:45-6:00 with HR around 145-150, but as you can see in the numbers, I had to significantly slow down to not have my HR cross 180 at easy pace in KK, and even then I was drenched in sweat like I took a shower. Another anecdote from the race day is of a very experienced American racer I met, who goes around the world running marathons through the year averaging 4 marathons per month, told me he would finish 3:05 but ended up finishing 3:30+.

  2. I trained with Pfitzinger 12/70 during February to April in Bengaluru, and it got scorchingly hot in summers in March and April in Bengaluru, though not as bad as KK in terms of humidity, but still I burnt out running 100k weeks in so much heat. I think the two-week taper was never going to be enough for me. So again, if you are training in summers, you need to account for a longer taper to recover. 

  3. Weight gain during training plan - I have posted about this in the sub a few months before too about eating so much and seeing my body change. My happy weight is around 64-68kg, but I peaked at 77kg on race day, gaining almost 2kg every month. Now it wasn't like I got 'FAT' fat; my diet was high in protein and replacement carbs, so it was kind of a very clean bulk which made me muscular, but still I practically turned into a jock from a twink in 5 months but failed to adjust my pace expectation accordingly. Now since the last 2 months, I am in a good calorie deficit and shed at least 5kg but feel much lighter than I felt during the training block and race day.

 

Race Day: As I explained, the race conditions were horrible, and I could only manage a 1h53m first half time, which was like my HM time from two years ago. Seeing that, I just gave up mentally and literally walked the rest of the race. I would have liked to say I just enjoyed the race vibes and cheering (which was actually great, no shade to the race organisers and people who came), but given the mental black hole I was in, I hated every minute of the race. I am not even sure if I finished in five hours. 

Since then I’ve been feeling better and taking a break from racing to focus on other aspects of life. I now run at most two days a week: a 10-mile run on Wednesday and a 20-mile run on Sunday. I’ve decided to skip races for the rest of 2026. I’m prone to mental health issues so while it might seem like a great idea to be physically active running 100k a week, the time it took away from my social and professional life, combined with the poor returns, made it counterproductive for me. You should also be mindful of this, especially if you’re prone to these issues, there is a sweet spot for mental health returns.

Let me know if you have any questions, I'd love to answer as I have always gotten great advice from this sub in last 2 years!

Did the thing

Chip time 3:21:02 (fell to the ground immediately after and forgot to stop my watch)

Missed my ambitious goal of 3:15:00 but grudgingly happy about the results. Ran my first marathon 6months ago (3:32:00) and caught the bug.

Need to figure out the mile 21-22 blowups (suggestions welcomed) but moving the right direction.

Ultimately a fairly boring course with little fan interaction and stomach complications from mile 5 on. Considering the circumstances, happy with this result.

Miles 21-26 were one of the hardest things I’ve had to do. But learned so much about myself in the process

Kudos to the mid-runners

Not calling out a specific poster or redditer, but I have often seen disparaging remarks/ comments on those who run over 4hour marathons. I’ve run three 4:30 avg. marathons - never stopping (minor pausing at water stations). My last marathon, I trained my heart out for a 4:15 time, and ended up spraining my ankle 3 weeks before my marathon, so I ran and finished 4:30 again, which was the only way to finish healthy and safe. Also had no shade the entire back half of the race. I was cooked. Either way, I could have maybe run a 4:15 marathon if weather and the safety of my ankle wasn’t in play.

Am I “capable” of more. Sure! But I am quite satisfied with my current level and my enjoyment of the sport, and I like to believe that I still ran 26.2 miles 3 times, and that it wasn’t just about a time. When I run my next marathon, I want to be healthy and have perfect weather, and if thats the case I hope to run close to 4 hours. But I still need to run the race Im given for that day in time.

Thanks for coming to my rant!

Finishing a marathon with a smile. Join us to talk Marathon training with no time constraints.

Hey it's a marathon, kind of ironic if it's timed right? When's the last time, time signed your checks?!!

How was your week, how far in the block and when's the next race? This will be a good mega thread to keep encouraging/critiquing 6 hour crew throughout the year.

Whether its shifts of motivation, some nagging pains, we've all been there! Let's keep each other engaged!

Diarrhea earlier in the day — can I still go for a run?

I have a run scheduled today and I would really rather not skip it. The diarrhea came in kind of suddenly but I feel ok now. Any thoughts? I searched for similar posts but most of them were about diarrhea after running lol

Fueling

**edit to answer some questions**

  1. I do have some history of running though I mainly was a thrower in high school. But I did some running in our training and did a few other sports. Running isn’t really new to me just the distance is.
  2. The heat here has definitely impacted it. I am running a lot less because of it. On a typical day without a heat wave I am still kind of hitting a wall at the two hour mark.
  3. I am working on checking some vitamin and lab levels to see if that could impact me. My family has a history of some deficiencies

.
4. Always electrolytes every day. I’m a very salty sweater.
5. I am in a deficit though because of this I have increased my deficit and protein intake a lot within the past two weeks.

Hello! I’m currently training for my first marathon and am having horrible me luck fueling. I don’t even know how to explain my issue. My legs or chest down hurt and aren’t tired, but I feel like insanely tired and weak at like miles 6-8. I’ve always been known for being extremely hydrated so I know that’s not the issue. I’m really struggling with this and it’s so upsetting. I feel like I could do more but I something in my body tells me not to or I’ll pass out.
Thank you!

Lululemon half tights great, except for sweat pouring into my shoes?

After feedback from an earlier post I purchased a pair of Lululemon half tights yesterday. Took them out for a long run this morning in 80’ with a 75’ dew point.

They were excellent, except my shoes were squishy wet from all the sweat. It’s better than wet shorts chafing my legs, but any solutions for this? Compression sleeves? Body Glide around the ankles?

What are the best running shorts you’ve actually used?

Hey, folks

I’m trying to find a good pair of running shorts and I’m realizing there are way more options than I expected. Some look great online, but then the reviews mention chafing, bad liners, tiny pockets, or the waistband riding up halfway through a run.

I mostly run a few times a week, usually 3 to 6 miles, so I don’t need anything super elite. I just want shorts that are comfortable, lightweight, breathable, and don’t feel annoying after the first mile. A decent phone pocket would be nice too, but I’d rather have comfort over a bunch of extra features.

For people who run regularly, what running shorts have actually held up for you? Do you prefer lined or unlined, 5 inch or 7 inch, split shorts or regular ones? Any pairs you bought and regretted because they looked good but felt awful on actual runs?

Maybe the real marathon was the friends we met along the way....

Random question that I was curious about...

My usual training run is a 1 mile loop in my neighborhood. For my long runs I just run this a bunch of times. Ror example, this morning I just ran the loop 14 times for my long run. Often there are other people walking this loop as well. Whenever I see someone I will smile and say "good morning" but I since it's a loop I will inevitably see them multiple more times (especially if they are going the opposite way) and I feel weird waving each time. What basically do now is just keep my eyes forward and kind of ignore them. It's kind of like driving next to someone you know and you keep getting stopped at all the red lights next to them. It's just a silly thing, but curious if other runners deal with this differently. I used to literally kind of smile and wave EVERY time I passed them, but then it just gets super repetitive and awkward ha ha.

Aiming for sub 3 hrs in Philly (PB 3:08 in Chicago last fall), does this training plan make sense or should I adjust it?

I (38m) have raced 6 marathons in the past 2.5 years with times ranging from 3:43 for my first to 3:08 most recently in Chicago last October.

The last 4 weeks before the taper for Chicago were each between 50 and 55 miles.

I’m running Berlin 8 weeks before Philly and plan to treat it like a long run both because of how it lines up in my schedule and because I expect Berlin to be really warm.

Two weeks after Berlin I’m planning on doing a 50k trail race with a friend, but similar to Berlin I’m treating it like a long run. My friend’s goal is just to finish and I’m going to stay with him unless our paces really start to diverge.

The rest weeks are scheduled around tattoo sessions (getting a full sleeve and I don’t want to sweat much for the week after each session).

My question for more experienced runners is does this schedule seem like it makes sense or am I either being too optimistic with my mileage goals or setting myself up for injury?

Im particularly uncertain about the 50k two weeks after Berlin and my legs being trashed in the lead up to Philly.

Heart rate training

I've been running for about 15 years with many breaks for mild injuries. (I've learned I have loose joints) I did a half a few years ago and wasn't as prepared as I should have been. It was all up and then all done hill.

Now I'm training for a mostly flat marathon for the first time. I've been really working on my heart rate and gaining mileage more comfortably. I ran at max HR for basically all my training previous to the half I did a while back. I've learned a lot and my cardio health is improving. I'm just worried I'm not getting enough miles in since I'm working HR only.

Week 9 and I'm doing about 14ish miles a week. I would love to hear your thoughts. 42F, ehlders danlos so I do a lot of PT to support my running.

Anyone else feel super depressed after completing a marathon?__

I ran my first marathon today. It was a solo. Havnt found any local marathons near me for several months.

I didnt start running with the intention of completing a full but as I got to 15 I said screw it, lets do this today. I hit the wall around mile 22. Slowed down substantially. Finished 4:45.

I know i was undertrained and I anticipated feeling like shit physically, what I didnt expect was to feel like an emotional wreck. Crying in the bathtub. (For context im a grown man with kids. Ive never felt like this before. Im the one thats supposed to be wiping tears)

I feel zero sence of accomplishment and feel like im a fraud. And that this was all for nothing, and all the training up to this point was stupid and a waste of time. Im left wondering why I wanted to do this.

Marathon wear and tear reduction?

Hello, I recently ran a marathon by myself just over a month ago. I managed to run it in 4 hours and 20 minutes however was unprepared in hindsight.

Cardio wise I was very much fine and probably could of gone quicker, my training consisted of doing large amounts of different forms of cardio such as hillwalking, running, swimming etc, however my joints most certainly felt it. Apart from 3 half marathons across the 3 months prior I didn't really stack up the longer runs. I also was using £10 flee market running shoes.

I am running a marathon with my dad at the end of August. I plan on running at his pace so don't imagine it will be much quicker than 6 hours. With this considered cardio fitness shouldn't be an issue, however how would I prevent it being quite as sore? I plan on getting propper running shoes which will hopefuly help my case. Would strengthening my legs in the gym provide good results alone? Or is the only way simply to increase training mileage? I thought this would be the best place to ask

Thanks in advance,

Emlyn
