I’m volunteer for a study that some uni researchers are doing, it is about the incidence of extra oxygen on cycling performace on athletes. During four weeks I have to go into a lab twice a week and do some excercises on the lab bike, some days with an oxygen mask and other days just sweating it on 20km time trial.
I’m getting close to 300, so here’s what I did today
Distance: n/a 5x5min efforts + 3min recovery
Comment: I was masked and breathing from a 200 litres bag full of air... good fun to watch
