Biggest mistakes: too long a stride, bouncing too much Even when your stride is one or two inches too long, your downhill speed can get out of control. If you are bouncing more than an inch or two off the ground you run the risk of pounding your feet, having to use your quads to slow down (producing soreness) and creating hamstring soreness due to overstride. Best indicator of overstride is having tight hamstrings (big muscle behind your upper leg).
