Trail running
48 mi
5000 ft of elevation gain
This ultra marathon takes place in August around the Island of Jersey, Channel Islands, UK. Trail Monkey are so excited to be taking over this iconic Channel Isles race after the great job Digby has done in creating this race and then keeping it going for the last 9 years.

At approximately 48 miles (77Km) and approx 5000ft of ascent this race circles around the island following the stunning granite cliffs of the North Coast to the golden sands of St. Ouen’s Bay and the South Coast.

We are going to be celebrating its tenth year in 2020, and the race starts from the Steam Clock in St Helier and follows the coastal road past the first check point at St Catherine’s Breakwater, overlooking the Normandy Coastline. The route then switches from tarmac to trail and the cliff paths start at Rozel; the route is stunning but challenging so do not be fooled!

Round The Rock has proved a favourite for many and they return year after year to soak up the relaxed atmosphere and testing course. Round The Rock is perfect race for those wanting to step up the distance and enter the ultra world or as training for a longer event.
