Route description

The race starts at our new countryside event base, Fuzzy's Farm which has direct access onto The Chiltern Way trail.

The first section of the route, to our checkpoint in Studham (11.6km), allows a fast start on friendly trails that for the most part keeps it flat, except for a short climb past Gaddesden Place at 3.5km.

From CP1 and continuing north, there is a steady climb until we reach the Dunstable Downs ridgeline and one of the best views of the day. The descent down into Eaton Bray (CP - 23km) is the longest on the course, but after a couple of flat kilometres to Ivinghoe Aston it's immediately followed by the biggest climb.

Once through the climb and at the 30km mark, the route passes the Ivinghoe Beacon viewpoint and follows what has to be the most stunning part of The Ridgeway to Aldbury, where CP3 will be found (35.6km).

Now the route climbs back into the trees to Ashridge Forest, a lovely section that takes runners through Berkhamsted Common towards the final pitstop of the day (43.6km) in Frithsden.

With the finish line in sight, there's an undulating 7km left to tackle, before returning back into Fuzzy's where a cheering crowd, cold beer and a big shiny medal will be waiting for you.
