i know its not all about speed but im putting the question out there to my fellow tredmill runners, having no confidence to run outside ive completed all my runs on tredmill, it hasnt been easy for me and i have total admiration for all ya roadrunners! just wondering what kind of speed you run at? im at 4.0 for brisk walk and currently 5.2 for a run. i tried upping to 5.5 from 7 weeks at 5.0 but too much too soon and a failed run put me off. im pretty sure the tredmill is set to kph. any feedback greatful for comparison. thanks!
