If you have two high intensity days, then yes, up to 60m and occasionally 80m but with three high intensity days, one very short, max 30m, one SE, and one combination day with a few starts and a very limited number of runs out to 80m
in any masters program, the number of runs must be carefully controlled and will always be lower than what is appropriate for a younger athlete. Even though the younger athlete can create a higher CNS output, it becomes more of a muscular and tendon issue for masters.
