We all know the value of long Z2 rides for building an aerobic base. But once that base is strong, is LT1 actually much more important !? Hearing about some leaked UAE trainings, and following Jonas Abrahamsen’s (one of the highest raw power pros) workouts on Strava, there’s a lot of LT1. Why is that?? For Jonas, there’s almost no Z2; mostly LT1, and a bit of LT2. Of course, we don’t want to spend another €300 on a handheld lactate meter, but the good news is that LT1 can be tracked pretty well with a power meter & HR, more or less. What do you think: is LT1 becoming the go-to intensity once the aerobic base is set?
