Some 1,000 participants gathered on a misty September 19 morning for the inaugural Challenge Henley ironman triathlon. Taking place on the River Thames, through the scenic Chiltern Hills, and nearby villages, the event included a 3.8K (2.4 mile) swim, 180K (111.8 mile) bike race, and 42.2K (26.2 mile) run. Challenge Henley-on-Thames is part of the Challenge Family global series of long distance triathlons featuring 13 races over three continents. The race was timed by our UK / Ireland distributor, StuWeb Timing Solutions, using the HDD System.
