Joe, One thinking about intensity and cycling race: All the training method promote training at Threshold or PMA during intensive session but when you look at power meter curve during competition, power gets up and down highly above and below the threshold because of riding in pack promote acceleration and bracking. Why does we do a big part of training mimicking it, like 5 second at 150-200% ftp and 5sec 20-30% ftp ? For me it would be a good idea to combine this type of training with low intensity training. What do you think about that ? Thank you !
