Got pic related today. Had a bike years ago and been a couch potato for quite a while. Very excited to get started (it's been storming all day) although I did get to take it out when it was quiet. Barely made it up the hill my street's on. Friend told me of a park that's about 20 minutes from me. I'm just wondering, if I'm regularly going out i.e. once a day for either as much as I can muster or around 5-10 minutes, how long would it take for me to get to the point where I can go for much longer? At least enough to cover a 3km (around 1.8mi) track.
