Charlie do you have a problem with a lower level sprinter doing 80-120 in SPP1 on a indoor track. For example:

SPP1:
4 weeks:
3x4x60

4 weeks:
4x70
4x80
3x100
3x120

4 weeks:
3-4x60

Indoor comp:
3-5x70-80

I don’t like the turns as they can lead to back problems and ham injuries, especially for males
