Qualifying ride for June done today. It was a ride I've been intending to do for some time, and which I was quite pleased with, so I'll do a proper write-up, though perhaps not today!
In the meantime, I should mention that Strava seems to have "stolen" a few tenths of a mile from both my last two rides. Garmin Connect and RWGPS both get it right. For obvious reasons, in the context of this challenge a discrepancy of this sort could be quite important. In the case of today's ride, having the ride recorded as 119 miles instead of 120 would matter since 120 is my long-term target Eddington number, but since I'm using RWGPS for that purpose it becomes more academic, though still irritating.
When I have a moment, I'll check my recent rides in detail to see if something really does seem to have changed.
