Maltese ultra-endurance athlete Fabio Spiteri is continuing to push the limits of human endurance, smashing through the cycling leg of his brutal ultra-triathlon challenge.After powering through a staggering 76km swim in 42 hours, Spiteri took just a short three-hour rest before getting back into the race, this time on two wheels.“After 76k swim, I cycled 390km in 24hrs!!” he shared, marking another massive milestone in the multi-day challenge.Earlier, Spiteri revealed he was the third athlete out of the water, just behind Jurand Czabański and Beto Stael, despite battling intense shoulder pain throughout the swim.The race forms part of an extreme ultra-triathlon format, where athletes take on punishing distances across swimming, cycling and running with minimal recovery time.Despite the toll, Spiteri remains among the frontrunners as he continues taking on one of the toughest endurance challenges in sport.Members of the public can contribute through Revolut on +356 99816248, via PayPal on rarmalta@gmail.com or through the official PayPal link.Donations can also be made through SMS on:50617312 (€2.33)50618075 (€4.66)50618923 (€6.99)50619260 (€11.65)or by bank transfer using IBAN MT40VALL22013000000050010082877.Would you attempt this?Photo: Fabio Spiteri•
