played around with Birling -1 and saw these Workout Levels:
- 5.8 level for TR’s Birling -1 which has 4x30-sec sprints and each sprint is 225% FTP for 20 seconds, and then 10 seconds decreasing from 225% to 30%
- 5.9 level if I use WorkoutCreator to make a copy of Birling -1
- 56.3 level if I use WorkoutCreator to increase the intensity by 133% (taking the 225% portion up to 300%)
