Training Tip Thursday

"Too much racing can compromise your marathon training. In the marathon training class in Chicago, we used to recommend that students race no more than three out of the 18 weekends at distances between 10-K and 25-K. Now we don't recommend any racing out of fear of injury. Races, nevertheless, can help you determine your fitness level and help select your predicted marathon pace. Here's a handy formula for predicting marathon time. Multiply your 10-K time by 4.66. (For instance, 40:00 for 10-K predicts 3:06:40 for the marathon.) First-timers, however, should take a more conservative approach and multiply 10-K time by a factor of 5. (For instance, 50:00 for 10-K predicts 4:10 for the marathon.) By choosing the more conservative formula, and starting more slowly, you're less likely to hit the wall."
