Phil @ Linz's Quarter Marathon!

When I was in track, the guys for the distance-races were training like this: run 100m normally, sprint 100m, 100m normal, 100m sprint. That about 10-20 times, a short break, and then another 5km run (whereas both the quantity of sprints as well as the distance for the final running was gradually increased each day. It's hard as heck, but obviously quite helpful for them. Yes, I was in the short-distance-team :P
