I’ve been seeing/hearing a lot of elite runners using “double thresholds” in their training. Maybe I’m naive but I’m curious what this exactly would look like (what a typical training week and more specifically what the workouts would be). I’ve also heard that it’s important to test blood lactate levels during these workouts to ensure you’re not going too fast or hard, but what should blood lactate levels look like on a day to day basis and in different workouts?
look up the training for the Ingebretsens
Woody Kincaid said in his post race interview at BU that his double threshold was 6 strait in the morning and 6 strait in the afternoon. Drew Bosley posts his double thresholds on Strava and they are usually something like mile 2 mile mile 2 mile mile everything at like 4:45 pace and then a similar session in the afternoon but slightly less volume.
I’ve also seen Bosley do 7 in the morning and 5 in the evening. Usually it’s alternating 16s and 32s, but I’ve seen 5x 16 in the evening as well
