I will doing the 2nd day of the hill training on the GPP DVD. Forecast is for rain. I have an isorobic exerciser and access to a BB court at the YMCA to use it at. Would I use the same volume listed (10x20m)? How about the amount of tension? I know for resisted runs you should not go over a 10 percent decrease in speed. Does the same hold true for Accel training. The hills show on the DVD looks to reduce speed more than 10 percent. Can you exceed this 10 percent rule as you are looking for more power than speed in accel training? AS for indoor tempo, does anyone have any suggestions for a good pool or treadmill workout to equal the tempo listed on the DVD???
