Looks like he left he forgot to pause his GPS on his bike whilst it he had a 6 mile transfer.
101.8 miles to 107.8 miles @ 60mph and lowest heartrate.
No doubt he's tried to sort that with UMCA but can't "fix" the Strava total.

I believe it can be sorted using the edit facility on Strava
Using the edit facility crop the ride from the days start point to where the transfer starts at 163.5km.
Upload a duplicate of the original ride again
Crop the newly uploaded duplicate ride from the days start point to where transfer stops at 173km.
You are left with 2 rides showing for that day on Strava - one showing up to the transfer at 163.5 km and one after the transfer of 119.7 km (292.7-173km). Total distance for the day is more like 283 km
Compared to Steves day 17 distance of 366.1km Tarzans lead after his first 17 days has been cut a fair bit. It will be interesting to see how he fares today against Steves day 18 total of 371.8 km.
