Quick backround. I started C25K last year, but around week 5 I got a stress fracture of my calcaneus. My last run before I had to wear the boot was the 20 minute one. I restarted again this spring, and I was doing just fine. However, I hit a wall at the end of week 5. I just cannot seem to run for 20 minutes straight! I signed up for my first 5k, and I did it this past weekend. I came in with an abysmal 44:42.
The other night I went out, and I could not seem to run more than 5 minutes at a stretch. Tonight I went out and did 10 minutes, and could do no more. I'm stuck here for about a month now. What is wrong????
The first thing I usually suggest in these situations is to slow down a little. Could be that you're a little over-confident because you've done it before. But the other thing that may be more important is that you're running in warmer weather. That can make a big difference depending on the weather where you live. I did a half-marathon a few weeks ago in 70 degree weather and did OK. Two weeks later I did 11 miles in 85 degree weather and had a really bad run. The cure is the same though - slow down.
Have you tried a run/walk approach? Start with a 3 minute run 1 minute walk and work your way up from there. Checkout Hal Higdon's website for more information. I have used several of his training plans and have completed 4 half marathons. I am now training for my first Marathon using a run/walk approach. ???? #www.halhigdon.com
