My positive experience with 7-days per week running, in terms of the improved running times, might be explained away by pointing out the benefit I am surely getting from 26 years of running in my legs. I'm inclined to agree with this theory but in the end, the reason doesn't really matter. What matters is 7-day a week running works well from a competition standpoint and from a health standpoint. It's easier on my body and I've found a great way to fit it in each day.
The bottom line is, 7-day per week run training, at least how I'm doing it, is much easier than the training I used to do. It's much less stressful on my legs and my body and yet I'm racing better than I have in several years. I believe this strategy can work well for other experienced masters competitors. I believe you can expect to lose weight, experience less trauma to your body, and even run faster than last season.
how to fit in 7 runs a week?
Here's how I fit in 7 runs every week. It's pretty simple - I get up 30 minutes earlier than I used to and get out the door - no matter the weather. For me, that means the alarm goes off at 5:00 a.m. This still leaves me with my lunch break and evenings for a couple more workouts each day - swimming, biking and in the winter - weights, yoga classes, and tennis (yes, I've been goofing around with indoor tennis).
