A half marathon with a difference; Can you run around two islands to return before the tide cuts you off?

21 kilometres | 2 islands | 1 extraordinairy race.

Thursday 22nd August 2024

The Tide Race


Racers will start on Tresco, just south of Plumb island at 1210. From here a short – but wet, knee deep run will take you to Merrick Island. A quick high 5 then back to Tresco to run around the entirety of Tresco Island’s coast path.

On returning to the start, you will cross the nearly dry sand bar to Bryher.

A loop of Bryher will put the finish line in sight. Then its just one more crossing of the sand bar back to Tresco. 

It’s not a race about how fast you run, more of how wet will you get!

A timing station on Bryher next to the Hell Bay Hotel will have the only cut off at 1410. Runners not passing this point before the stated time will cut 4km from their route and head directly across the island so they can cross the sandbar safely.

These Islands are part of the Isles of Scilly Area of Outstanding Natural Beauty; whatever your speed, this will be a stunning day out .

The Race

Important Information

Take the time to think about the whole event. Although the race is under 3 hours long, most people will probably choose to spend at least a couple of nights on Scilly. It is possible to do a day trip, though flying will be the best way of achieving this with minimal stress.  

I have outlined some of the key points below, but you should also read our Frequently Asked Questions before signing up.

Travel & Accommodation

You will need travel by air or sea to Scilly – you can only drive as far as Cornwall. You will likely need accommodation – there are campsites, B&Bs, hotels and self-catering cottages, but accommodation books up early.

There will be multiple tripper boats over to Tresco at the start of the day. These usually start from about 1015. It is better to get an early boat rather than miss the last boat.

There will be a water station at the start line, please bring your own reusuable cups. Better still, bring a water bottle and leave it by your bag. A waterproof bag is recommended.

Frequently Asked Questions

What will the terrain be like?

Is there an age limit?

Yes, you must be at least 18 to take part. There is no maximum age limit. 

Can I take part in a team?

Yes. It is the same price as two separate people though as you will both get souvenirs. You can ‘pass the batton’ at Merrick Island.

Can I book in on the day?

Yes. Before 1130, if possible please try to book as soon as you know as it make the organising easier.

How strict are the timing cut-offs?

Very. We want everyone to enjoy the run, but also to be safe. If you don’t get to Hell Bay hotel by 1410 you will take a short cut back so you can cross back to Tresco safely before the tide is too high. 

Will there be energy stations?

No – you need to plan and carry what you need for each stage. You can leave water/snacks with your bag at the start line as this also doubles as the middle and end of the race.
