Food poisoning, punctures, mechanicals, snow, fog, a full-blown storm, 5am alarm clocks, 8+ hour days of work sandwiched between a relentless sea of dark mornings and dark evenings on the bike - this was Chris' world.
But through the ups (all 55km of them) and downs, he always had an unwavering determination to reach that finish line.
What Chris hadn't banked on was just how much support he would gather to drive him to the end.
What started with the company of a few close friends soon extended to handfuls of strangers offering wheels to sit on, homemade treats and kind words of encouragement.
None of us appreciate how far Chris' story would spread. On Day 103, we put a message out asking the local cycling community to come join Chris for his regular morning laps at London's Regent Park. More than 60 cyclists turned up to ride, a much-needed boost in that last week.
It's hard not to be moved by Chris' reaction when his ELEMNT officially ticked over at the 107km mark. The man is an utter legend, and the lengths he's willing to go to get recognition for a worthy cause is truly admirable.
