Interesting. I’m in my mid forties and I know I’m overweight by up to 10kg right now (currently around 85kg and just worked out BMI at 26.6 😯 ) I tend to avoid these sort of posts but it seems I’m not too far off the OP who’s been called out on size and fitness by a few posters so far.
I’ve recently started Garmin & Strava’ing my commute after playing idly with it a couple of times and getting the bug. I spent several months off the bike earlier this year due to injuries and managed to forget about cutting my eating. Ho hum.
Anyway, I habitually ride on the hoods, my bike is a fairly heavy steel CX with average wheels and 28’s, geared CX style 36/46 front and 11-28 back.
My commute is between 4 and 5 miles depending upon exact route (varies) and is in City conditions. I do wear bibs but with a backpack full of work stuff and loose running tee. I tend to ride it as a series of sprints, currently moving time is around 14 mins for the route. TBH, I’m good at instant power. It’s endurance that I struggle with at times, and that’s what I plan to work on personally although this commute does’t really lend itself to that, as the simple need to stop for junctions etc means you can’t keep a steady speed for longer than a couple of minutes.
My averages are around 17mph, and I usually hit around 30mph from a traffic light start on one particular stretch. Monday last week I hit 33.3mph on that stretch, taking 3rd overall on the segment (says Strava). OP, keep pedalling! If you really can’t get the bike any quicker, maybe take a look at setup… 🙂
