Subject: RE: substitutionsWell, here's what I think. The number of miles that a treadmill or stationary bike reads is complete garbage (the same goes for the speed, because they are related ), so if people are training in miles they shouldn't be using numbers from their machines. However, if they are training by time then any time spent doing the activity, regardless of whether they are inside or outside, is valuable and should count.
Maybe a simple conversion could turn these minutes into pseudo-miles. Take the average speed you perform at outdoors, and use that to convert minutes on a treadmill or trainer into the equivalent distance you would have gone if you went outdoors. Does that make sense to anyone else?
