The season opener of the Ultra race calendar, this 43 mile point to point race is an event not to be missed. It has a great reputation of selling out quickly and its track record is known far and wide. Taking runners through the beautiful Buckinghamshire countryside and across the M25 by bridge, the race continues to the quaint village of Denham and then along the Grand Union Canal tow path to the Little Venice canal basin in the heart of London, near Paddington Station. This year, the race is going to be fully tracked and interactive, allowing friends and family to follow your progress from the comfort of their own homes. Additionally, it is a qualifying race for Ultra-Trail du Mont-Blanc, with 3 Endurance points awarded by ITRA. On the start line, it's not unusual to see runners from all over the world, making for an unforgettable experience.
