Kilian Jornet announced his retirement from running on Wednesday, with the intention of taking up fishing instead. Most people realised it was an April Fools’ Day joke and we had not seen the last of the famous Spanish runner and mountaineer.

But now he said the video, which advertised a fictitious Salomon fishing rod in the style of their carbon running poles, had an ulterior motive, beyond amusement.

“The goal was to call your attention to a contest we are doing to raise funds to support the fight against Covid-19,” Jornet wrote on his blog.

“I’m going to sign and give away three pairs of shoes that I've used in mythical races (Sierre Zinal, UTMB, and the Golden Trail Series finale) to a lucky winner who donates,” he wrote. “All donations will be made to the Solidarity Response Fund de la World Health Organisation (WHO) and will support WHO’s work to track and understand the spread of the virus.”

To win, you have to make a donation, leave a heart in his Instagram post’s comment section and he will pick a winner at random, upon proof of payment.

This is not the first coronavirus related act from Jornet. He made his films Summits of My Life free for a week to alleviate the boredom of self-isolation and lockdown.
