MYSTERIOUS: Bike check jack thompson s project 1903 custom 2 speed specialized roubaix - What They Never Told You

Jack Thompson, ultracyclist, standing next to his custom 2 speed Specialized Roubaix SL8 ahead of his project 1903 challenge. .

Jack Thompson rose to fame during the 2021 Tour De France when he not only gave the peloton a 10-day head start in the race to Paris, but after covering 3500km/2175 miles, beat them to the Champs-Élysées by three days, which he called 'The Amazing Chase'. Since then, Thompson has racked up several incredible records, including a 1,000,000m elevation odyssey in 2022, along with a whole host of FKTs (Fastest Known Time) across Australia and Japan.

Now, Jack's back, and it is another bonkers Tour De France theme challenge for 2025. Jack will be taking on the original and notoriously brutal 1903 route. While only 2428 km/1500 miles, which is short compared to modern standards, he will attempt to complete it in the original six-day format, meaning an average of 413km/256 miles per day. Keeping it even more true to the day in which riders would stop to change cogs for the climbs, Jack will be trying to complete that mileage on a custom two-speed Specialised Roubaix SL8.
