I'm a HS junior who's been running for 5 years. I've started to have a slump in performances due to chronic injury. I can't seem to get over 40mpw without getting some sort of injury. I've had stress fractures in both tibias and one metatarsal, severe tendinitis in my feet, plantar fasciitis, and chronic hip imbalances that I can't seem to fix with lifting and core strengthening. It just seems to be something new every few months.
If I didn't love running as much as I do, I'd quit, but that's not the case. I just love the sport too much to give it up. I've been able to come so far from when I started, and I can also contribute so much to the team that I can't quit. I need a long-term solution so I can keep running (perhaps with less improvement), while not getting injured.
My current idea is to only run workouts and races and substitute all of the other mileage with cross training. I could do a week like this:
Mon - AM: 30min stationary bike; PM: 60min stationary bike
Tue - AM: 30min stationary bike; PM: track workout (tempo or 3k-5k pace)
Wed - AM: 30min stationary bike; PM: 60min stationary bike
Thu - AM: 30min stationary bike; PM: track workout (speed or 800-mile pace)
Fri - PM: 30min stationary bike
Sat - Meet, 2-3mi of races
Sun - AM: 90min stationary bike or run (if I feel fine)
Would the morning and afternoon stationary bike cross training along with track workouts be enough to be worth 40mpw of running?
PR's 800 - 2:05, 1600 - 4:34, 3200 - 9:55
