ya i understand sled is more intense than hill work, i was originally going to do about 60% of the volume that cf recommends but then i lowered the sled work volume down to 50% when i learned that sled work was more intense. when i planned it out i spread out the lowered volume over the whole week instead of just having one lowered volume day. tomorrow is my first non sled speed day and i have the total volume at 400m but a lot of it is sub max, this is about 60% of what cf recommends, i also do the med balls at 60% of the cf volume, so the 50% i do on sleds factors in that they are more intense than hills.
overall i feel i am handling the speed volume pretty well, i have more of an issue with tempo which even with slowly raising the volume i am having some lower leg problems that appear while i am running tempo sessions but disappear afterwords. i have been able handle the sled work so far, albeit during my highest volume week i missed a speed session, so that week only had two speed days
