I hurt my hip flexor and I was told I can't run for 4 weeks by a doctor. Prior to this injury, I ran 50-60 miles per week in the winter and I ran 4 mile tempos at 5:40-5:50 pace. My first race I got a 2:10 in the 4x800 and 10:40 in the 2 mile, I was thrown in this race at the last second . I will be riding on a stationary bike for the 3 weeks. How will this affect my performance and what are some things I should do to maintain my fitness?

It will depend on a variety of factors but generally, since you are a younger runner, taking 4 weeks off will hurt you a bit but not a lot. It sounds like you got in some good base training (nice work!). I’d say to keep on the stationary bike. Biking is a very effective way of cross training. Throw in a couple days of swimming and core as well, and you are golden. When you come back it’ll likely take you 2ish weeks to return to fitness, maybe even less. Good luck and stay motivated!
