He's riding a completely different ride. He isn't riding it for time per se but rather amount of days. Yellow Jersey at the tour de france rides for total elapsed time. Completely different levels of work involved.

For example - it says Morton was riding for 12 hours a day. Same riders on tour would be doing that ride in significantly less time. A completely different ride and bicycling capabilities.

I'm not diminishing what he has accomplished (which is awesome) just pointing out the differences.

For example: Sepp Kuss who won the stage the other day (https://www.strava.com/activities/5612150086) effort vs the ride by Morton Lachlan (https://www.strava.com/activities/5595556740). Morton's riding a roughly different ride (same terrain but different set up) and riding by about half the speed and 30% more distance.
