I’m getting into running more seriously after a long athletic background, but I’m pretty new to structured running training. I grew up playing competitive soccer at a high level and was always known more for speed, repeated sprints, and being able to cover a lot of ground.

After that, I spent the last few years focused heavily on gym training and hybrid/CrossFit-style conditioning, so I’m not starting from zero fitness, but running-specific training is definitely new to me. I’m trying to transition from “athletic person who can push through a run” into someone who actually trains intelligently as a runner.

A few things I’m curious about: how would you recommend building mileage without getting hit by overuse injuries? Should I prioritize easy runs/Zone 2 at first, or is it okay to keep some speed work in? Any advice for calves/Achilles adapting to more running volume, especially with a midfoot strike? How much should I care about cadence/form early on?

For anyone who came from soccer, lifting, CrossFit, or another sport: what helped you make the jump into distance running?

I want to take running seriously and build this the right way instead of just trying to out-grind bad training. Appreciate any advice, reality checks, or beginner mistakes to avoid.
