A while ago, I posted an example of how to edit .gpx and .tcx files when there might have been a small corruption of the ride file preventing it from being uploaded to Strava. See it at http://www.briansutton.uk/?p=330. This post concerns the situation when you have been on a long ride, and the battery on your first Garmin Edge (orContinue reading “Merging Strava and Garmin ride files to create complete courses”

Bicycle helmets – again!
I own up to having a hobby horse. My cycling friends will be surprised to know I don’t wear a helmet when riding it (!). The hobby horse, of course, is my insistence on the advisability of wearing a helmet when cycling – always. But I have today been assailed by several articles that IContinue reading “Bicycle helmets – again!”
Zwift off-piste course choices
In case this helps anyone who gets bored after a day or two with any of the Zwift courses, you can change your preferences to force Zwift to give you London, Watopia or Richmond on any day of the week, not just the allotted ones on the monthly schedule. Take care, and be aware ofContinue reading “Zwift off-piste course choices”
Monday, Monday…
Various connotations for an alliterative Monday morning come to mind! One is that great song “Monday, Monday” by The Mamas and Papas (https://m.youtube.com/watch?v=iIo8_bMFwxs or https://m.youtube.com/watch?v=-TFddCrHlPY) I remember driving to back in the 60s, sometimes from my home in Tottenham into central London in the days when you could park free in the old Covent Garden,Continue reading “Monday, Monday…”
Relativity matters (!)
I responded to this question on Quora.com on Sunday 19th Feb 2017 The physicist J.A. Wheeler stated, “Matter tells spacetime how to curve. Spacetime tells matter how to move.” Was he right that spacetime curves? The simple answer is “yes”. But my friends wouldn’t expect me to stop there! John Wheeler had a great wayContinue reading “Relativity matters (!)”
Avalanche matters
Now that my son Tom will be ski-leading for the Ski Club of Great Britain in Verbier later this month, including some off-piste days, or at least with a greater proportion of off-piste than our usual family skiing, my mind turns towards avalanche safety and the recent sad news of the fatal avalanche in aContinue reading “Avalanche matters”
Using TextWrangler to edit Garmin, Zwift, Tacx and other .fit, .tcx and .gpx files
On the lost ride retrieval topic, I haven’t yet found a way to locate any surviving Tacx data from my iPad, but I have several times had cause to edit a Garmin ride file which wouldn’t upload to Strava. Typically this has been because the ride data file has been corrupted, albeit quite innocently. OnContinue reading “Using TextWrangler to edit Garmin, Zwift, Tacx and other .fit, .tcx and .gpx files”
Recovering from lost turbo rides in Zwift
Recently I have lost or partially lost Tacx rides using their trainer software on my iPad, and also had one lost Zwift ride. For Zwift there is a way to recover partial rides if the software freezes, by peering into the iPhone or iPad with a laptop program called iMazing. It’s a chargeable program, butContinue reading “Recovering from lost turbo rides in Zwift”
Using an ANT+ dongle for turbo training
The Tacx Flow, and other smart turbo trainers transmit and receive on Bluetooth as well as ANT+. So for a handheld or laptop with Bluetooth you should be OK with a smart turbo (although there does seem to be a Tacx limitation on the number of ANT+ channels available such that if using a Garmin GPS ANDContinue reading “Using an ANT+ dongle for turbo training”
The Brachistochrone problem
Brachistochrone I was struck by this GiF recently, at: http://imgur.com/5t32VJU This little video shows three possible paths – the straight line (the shortest), a path that descends quickly and then becomes flat as it gets to the destination, and one in between, looking more elliptical* in shape. Ever wondered what downhill profile of roadContinue reading “The Brachistochrone problem”
