I had a look at the "treadmill version" on the c25k website, but it has runs lasting < 2 minutes. The treadmill that I want to use, is very slow changing speeds - I'm concerned that going from walk to run (or back) could take several seconds, and out of a 90 second run, 10 seconds is a lot.
Should I not include the transitional time in the walk/run duration? Or should I count it as part of one or the other? It seems like the rapid walk/run transitions are designed for running outdoors, where it is easy to switch between them - how can I adapt the plan to work with a treadmill?
