Ok daft question probably, but you lot are the r/w gurus has anyone tried 3 mins / 6 mins or similar for real endurance events, the walking section being a cheat as. It's more of a fast march instead of a more relaxed walk.
i was experimenting in my 2nd marathon of the weekend on Sunday, and was playing around and marching at 10 min per km, for about 700m, then gently jogging the last 300m of a km, and repeating, and I found this an incredibly efficient way of plodding along at Easily over 4 mph, and frankly for a 100 mole ultra if you can nibble up 40 odd miles like thst without it taking to much out of you then it's worth considering.
So.... I was near the back on day 1, near the back again on day 2.
There were 60 something runners on day1, and 50 something runners on day 2. I was last if you add together the times of the 34 of us that did both days, but out of those 34 two came in behind me on day 2, so I beat 2 of the other 33 on the 2nd day just not by enough time to not be last in the combined totals, oh well!!
