Paper calls for endofibrosis to be classified as “an occupational disease” for professional cyclists

A research paper outlines the risks of failure to diagnose – what is a rare disease for the wider population – in professional athletes and cyclists

A research paper has just been published calling for endofibrosis to be classified as “an occupational disease in the case of professional athletes or cyclists”, after the two cyclists of its case study were presented with the possibilities that their professional careers might be over.

Endofibrosis is an uncommon disease in which “the lumen of the artery becomes progressively occluded due to a thickening of the arteries intima.” Essentially, the flexed position on the bike and the long periods of high intensity effort can cause a fibrous tissue build-up, which narrows the artery and can lead to pain, weakness, numbness, cramping and/or swelling of the thigh.

I’ve been hooked on bikes ever since the age of 12 and my first lap of the Hillingdon Cycle Circuit in the bright yellow kit of the Hillingdon Slipstreamers. For a time, my cycling life centred around racing road and track. 

But that’s since broadened to include multiday two-wheeled, one-sleeping-bag adventures over whatever terrain I happen to meet - with a two-week bikepacking trip from Budapest into the mountains of Slovakia being just the latest.

I still enjoy lining up on a start line, though, racing the British Gravel Championships and finding myself on the podium at the enduro-style gravel event, Gritfest in 2022.
