No, I wouldn't fund this because it's so obvious that one is weight bearing and one is not that all your 'myriad confounding variables' don't even matter.
The recovery cost of running so well known that every triathlon coach warns all their athletes, novice or pro, to be CAREFUL during the run. It's weight bearing, and it's hammering.
Pro marathoners race only ONE 2hrish marathon every 4 months (if not 6 months) because of the recovery cost. Compare to TdF riders who will ride 6hrs nearly every day for weeks.
