British vegan ultrarunner Dan Lawson, 44, is currently attempting to set a new record running 874 miles across the island of Great Britain, from the northern tip of Scotland to the western tip of Cornwall, England, in less than nine days. “This will be his biggest running challenge yet,” a crew member said. “He would like to beat the current record of nine days, two hours, 26 minutes—the phenomenal time by Andrew Rivett. He is well-aware of how hard this will be and will put everything he has into it.” Lawson is currently completing his fifth consecutive day of running an average of 90 miles each day. The challenging route includes traversing the Cairngorms mountain range in Scotland and Lake District mountains in England. Dawson already holds multiple world-class race titles, such as Britain’s Grand Union Canal Race, the 400K Ultra Gobi Race, and the UltraBalaton 218K. As further evidence that a plant-based diet is optimal for endurance sports, last month, 53-year-old vegan runner Catra Corbett set the fastest known time on the 310-mile Muir Ramble Route course through California.
