A while back I was interested in exactly implementing a Burgomaster protocol on my trainer…so I was trying to figure out exactly what you are. The advice I got most often was ‘Just put your trainer in slope mode, move the resistance up to 80% or so, and go all out for 30 seconds’. That works ok.
But, having done a Wingate test, and having done an all out 30 second print on my trainer…I would say the Wingate test is a darn sight harder. So there you go.
