I’ve done a 10 mile each way commute for about 7 years now from NW London into the outskirts of London town. A few things I’ve thought about:
1. Use a relevant bike. I use a road bike with mudguards, decent tyres, rack/panniers, dynamo lights and a hub gear. Means you rarely have to think about whether the bike is working and even worse cleaning it! I can’t remember the last time I had a puncture (28c schwalbe Duranos).
2. You DONT have to do it everyday. Sometimes I ride 2 times, somtimes 5 times a week. All depends on whether I’m going out after work and how my legs feel. Always have the option of the tube. Plus eventually you’ll miss it if you don’t do it at least 3 times in a week!
3. Keep clothing simple. I have tons of bike clothes, but I tend to use the same one set for commuting. Means I dont need to decide in the morning! Merino baselayers and Torm sportwool jerseys are good: dont smell. This may sound weird but I also think about how long stuff takes to put on/off. I dont want 4 layers to take off and hang up. I just want 2.
4. Pick a good route. No-one wants to sit on an A road getting buzzed by traffic for 40 mins. Even in London, you can always find a less busy route you’ll find more enjoyable.
I’ve never found my commute stops me riding at the weekend. Still want to go out on the club run every Sunday. Thou if I’ve got big weekend of riding planned, I’ll just get the tube in for a few days.
