There is some great info here,but obviously non is definitive. One of the questions I dont really see answered is about the debate of distance versus ascent. I have heard that for big hilly ultras, such as PBR etc that it is better to do 10,000 feet per week of climbing than just sheer milage. I have a friend who is on 90 miles per week and I think forumite Steve S also does vaste distances but apart from being obviously very fit, will that alone translate into all the up and down hill needed for a PBR or something similar. I am currently having a year out and doing 3.5 miles per week (not good ultra prep. Come October when I start PBR training I,d like to think I can put the ultimate plan into action!!
Any views on climbing v distance?
