And a new course and world record! 333.6 miles/537km (old U20 course record 270mi/435km and old WR 290mi/467km)

Last full lap…

A power nap to regenerate for the finishing circuit

World U20 record (290mi/467km) resoundingly broken! Harry now on 320mi/515km with over 3hrs to go. xitter.cf/HToms_WTTC/status/1720…

Getting warm now! Less than 30 miles till the world record, and 6.5hrs in hand still, after a bacon sandwich break.

Last night-time lap, next pictures will be in the sunshine! 347km, 13h17. Still looking good.

12h37m, 330km. 140km to go for the record. Looking forwards to sunrise and some warmth, but not to the afternoon heat!

10hrs in, 265km done and slowly moving up the rankings. 205k to go for the U20 world record.

200k done in just 7h20. But it gets exponentially harder with fatigue from here…

First “long” stop, after 120k and 4hrs. 10 mins for dinner, device charging and quick bike check. Now into the long overnight hours…

15 second pitstop to reload with energy drink and sugary snacks! Still lapping at 30kph, some way ahead of the 25kph target.

Second lap- gets very dark very quickly in the desert!

First lap done, coming in for a visor change for nighttime. Going very well, first lap a bit faster than planned.

They’re off! See livetrack.garmin.com/session… for live tracking

Registered and bike all labelled up. 20 mins to go.

Course inspection ride, with some of the world’s top ultra cyclists, who were all super-friendly!

Arrived in Borrego springs, bike reassembled and weather looking good. Course inspection ride tomorrow!

Last day training in the mountains before returning to the desert

Training ride in big bear lake- amazing conditions and stunning riding

First training ride in Palm Springs- getting used to the desert heat then cooling off with the descent from the aerial tramway.
