I hear a lot of talk about running downhill. I understand arguements from both sides, those that support it and those that oppose it. However, I have access to a 100 meter hill that by my calculation is about a 2-3% grade. For years now we have incorporated a set of weeks devoted to downhill running once per week. We have seen huge improvements in our sprinters and hurdlers (especially hurdlers) in the weeks during and following our downhill runs. We don’t use the entire 100 meters, typcially just 30-50 meters. We typically spend 5 weeks running uphill, then 3 weeks down, 2 more up, and 2 more down. It’s just something that works for us really well. In my opinion, the slight grade allows for more normal running technique. Also just from experience, boys take to downhill training much better than girls. Again I’m lucky I have a slight hill grade and a nice surface to use, and it works in our system.
