To put this rondo on the map, draw a circle around the heart of Britain - more than 700 miles, two countries, five thousand years of history.

To put this loop on the map, you’ll pass numerous beautiful cycling highlights along the way. Starting at Avebury Stone Circle, you’ll cycle east through England, passing places including the Chilterns, Wimpole Hall and Gardens, Earith Lakes, Huddersfield Victoria Tower, and Marsden Moor.

Once you’ve crossed the Mersey by ferry at Liverpool and entered Wales a little farther on, the route really starts to climb, taking in Halkyn Mountain, Moel Famau, Moel Arthur, Lake Vyrnwy, Bwlch y Groes — the highest paved mountain pass in Wales — Moel Famau, Llyn Clywedog, Graig Gogh Lake, Caban Coch, Epynt, and Blorenge.

At the Severn Bridge near Bristol, you return to England for the final stretch back to Avebury Stone Circle.

After 700 miles / 1100km (road route) or 750 miles / 1200km (gravel route) in the saddle, you arrive back in Avebury. The loop is complete!

Narrow tires? That’s absolutely fine! The route is entirely on paved roads.

Gravel bike? Then take the gravel route, which is mostly unpaved and runs along byways, forest tracks, and the roughest gravel roads in Wales and England.

"An iconic round, perfectly mapped out by hand into a super fun, bike-friendly route full of beautiful highlights and magically shaped into a unique circle on the map. "
