I was curious if there's any science to this.. indoor sessions feel like much harder work, & it's much mentally harder to do a long session.. wheras outdoors the same H.R's are attained far more readily, and long sessions are enjoyable.. (granted indoor training has it's uses)
Is there any physiological difference associated with the blatent psychological difference e.g. endorphin release .. something associated with the fact that actually covering distance is something our ancestors relied on to survive.
