If you want to make a bit of $ just by riding a bike and also get to know your VO2 max plus other cool science stuff, you should do this study. They’re still looking for 13-15 participants!
It’s three visits (lasting around 2h each) and you get $50 for each. The first one is VO2max test, lung test, body scan, and then a 5k TT. The next two visits consist of a 20k TT.
The downside is that you have to do the tests with a thermometer measuring your core body temp, and that thermometer is stuck up your nose and down your throat. It’s not the worst!
