I've got a group training run today. We're doing hill repeats, for 24 minutes, after a warm-up which will likely be a mile.
The hill repeats workout I already have repeats for a specific number of times up a hill. What I need to do is find out how to do a repeat that's based on time, but won't start until we get to the base of the hill and won't end until the 24 minutes is done.
I have tried several times and cannot figure out how to do this. I use my Garmin connect app on my phone or on my desktop to set them up.
