Absolutely.

Set up by the legendary Gurkhas, who are celebrating 200 years as part of the British Army this year, Trailwalker is the ultimate physical and mental challenge.You'll need to motivate and encourage each other from start to finish to get the job done, so be prepared to pull together to achieve something astonishing.

The other vital team is your Support Crew - friends and family who'll meet you at checkpoints along the route to provide supplies and encouragement. Their help carrying your gear and giving you morale boosts you really cannot do without.

It'll be one of the hardest things you ever take on, but the sense of achievement you'll get when you cross the finish line will blow you away.

The route


The route starts at the Queen Elizabeth Country Park and ends at Brighton Racecourse. Along the way you'll follow grass and flint tracks across the rolling countryside, passing stunning dry valleys and pretty villages. There are also steep climbs up scarp slopes, and dramatic views from high points. It's a cracking mix.
