okay so I wanna run my first marathon in oct. the longest run I have ever done was 11 miles 2 months ago. I remember training for a half but had to cancel last minute bc my cat passed away. I did not run for two months until 2 weeks ago got back into it. I just ran a 5k and it was 34:33 and my fastest 5k ever is 29:32 a few months ago I ran a 10k in 1:00. do you think I can run a full marathon in 3 months. I know I could run a half if I had 2-3 weeks to prepare. I already signed up and I'm just planning to follow my Garmin plan but I wanna know if this is even possible.
