i think smallfurry has done some self testing on this.
and he's a scientist, so i'm prepared to trust that.
much in the same way i have made up my own training plan and sent it to a friend who is a fitness coach with the GB swim team, (oh and happens to be running the UTMB) she says it'll work so i now trust that and will stick to it, with the addition of a recovery run once per week and some running specific strength training.
