First go at treadmill running this morning. Much better experience than I imagined going to a gym would be. I was probably the oldest there but a range of ages really and pretty few in numbers. I did 45" after a 45" swim and that felt like enough.I had it set at 5....but couldn't work out the equivalent to my outdoor running which is about 8"/k.
It was easier, warmer, and boring in terms of scenery. I will use it a couple of times a week for part of my red January and you can sign up just for a month, so not tied into a year.
