The Event Itinery

Thursday 29th August. 1400.

First off – The Guided Swimrun session, a fabulous opportunity to experience what Swimrun is all about. A leisurely Swimrun guided by event organiser Wez Swain and an excellent introduction into this land and sea sport. The course will involve 3 swims and 5 runs, totaling about 600m of swimming and 5km of running, with plenty of chat and support along the way. Not a race but a social event and a chance to ‘dip your toes in the water’.

1330 – Race briefing for the St Mary’s Full and Half courses

Saturday 31st August.

1430 – Keeping the kids involved there will be a Junior Swimrun, which has four separate routes for varying age and ability brackets.

Frequently Asked Questions

What will the terrain be like?

All islands have short steep hills. 95% of the run is on the coast path or trails, with a small amount of running on beaches/sand and road. Although the maximum elevation is only about 93m there are plenty of ups and downs throughout the day – it is hillier than you may think!

Yes, you must be at least 18 to take part in the Guided Swimrun, St Mary’s Half, St Mary’s Full and Archipelago. There is no maximum age limit. The Junior Swimrun is for all ages.

Can I take part in a team?

Yes. You can choose to be in a pair or solo. Pairs must keep within 10m of each other. A bungee cord connecting both is advised for the swims 

How strict are the timing cut-offs?

Very. The cut offs are for everyone’s safety. Please train hard, we prefer to be nice to everyone.
