🌊 The Tide Race – 10km

Friday 14th August 2026. £45

The Tide Race returns in 2026 for one of the most unique running events in the UK.

This spectacular 10km race begins on the island of Tresco. Thanks to a rare alignment of the sun and moon, the tide drops just long enough to reveal the famous sandbar linking Tresco to Bryher.

The Race starts at 1157.

If you are staying on St Mary’s you will likely need to get a ‘tripper boat’ at 1015. This will get you to Carn Near at the south of Tresco for 1030. it is a 2km walk to the start area. If you get the 1115 boat, you will need to run to the start.

Runners will:

• Start on Tresco

• Run across the temporarily exposed sandbar to Bryher

• Complete a full circumnavigation of Bryher

• Then race back across the sandbar to Tresco — before the tide returns

⏱️ Time Limit & Cut-Off

• Runners have exactly 2 hours to complete the course.

• Low tide is at 1257. The Race will start at 1157 and finish no later than 1357.

• Any runner who finishes the Bryher loop with less than 15 minutes remaining will not be permitted to start the return crossing due to the incoming tide.

This strict cut-off is in place for safety and is non-negotiable.
