My commute has a big climb that varies from steep an short to long and gradual and a second climb that is short and steep both ways. Before I started commuting, I did the first big climb a couple times to get used to it. Since then I don't do any training, but sometimes treat my commute as training. Some days I will push myself a bit harder on the longer steady climbs or on the short steep climbs. I track my performance with Strava to see my improvement. Over a few months I saw steady overall improvement. Anytime something causes a break in my commuting I feel it again when I get out and build back up. When I actually have time to ride on the weekends, I try to do some longer climbs to work on conditioning, but I don't consider it training for my commuter per-say, just generally trying to improve my fitness.
FedericoMena, how long have you been riding this route? I had a hilly commute years ago and rode it every day. I used to huff and puff, the effort was on my mind. After four weeks, I noticed I was getting to the top without thinking about it and without struggling.
Been riding it about a month now. I do it once or twice a week. I wish I *had* to do it everyday, but since I work from home, sometimes I just have to look for an excuse to go downtown.
I'm quite happy about my progress, to be honest. Today I rode another route which I would have thought crazy a month ago, and well, now it's done, at least the first time
