The Xtreme Terrain Triathlon and Xtreme Terrain Duathlon have now merged into the one-day multi-event Xtreme Terrain Festival which is organised by allabouttriathlons.co.uk Held at Hawley Lake in Camberley, Surrey on 22 September, this extravaganza will host no less than seven events including triathlon, duathlon, aquathlon and 10k running.

This off-road event will make the best use of the Army training land and lake, using tracks and woodland paths. Depending on your chosen event of either full distance or sprint, athletes will need to complete multiple laps of the swim, bike and run. The swim course also involves a half-way exit and re-entry into the lake.

Other facilities available on-site include showers, free parking, plenty of portaloos and access to the permanent café. Snow + Rock are proud to be headline sponsors of this huge event which expects to attract over 1,000 athletes. Entries from USA and Germany already make this a truly international event and we hope to see internationally recognised duathlete Sam Gardener returning to claim first prize.
