Ive just done 5k on my excersice bike .in level 10 mode..(sort of middle of the road level ) i intended to only do 2 minutes as my goal is to do 2 minutes on the bike each day if i can . 5k for me took me at level 10 or plan 1 took 15 minutes and 2 seconds with 60 seconds recovery at the end. i didnt expect to be able to go past 2 minutes so i was surprised.
