Scilly110 – The Ultimate

Scilly110 is the pinnacle of Scilly60 Events — an exclusive 110km ultra marathon reserved for Scilly60 finishers or very experienced endurance runners. (If you have not already completed Scilly60 please email Wez a couple of running highlights showcasing your experience - hello@scilly60.co.uk)
This is the ultimate test of strength, resilience, pacing and island-running mastery.

Competitors begin with a full loop of St Mary’s before crossing by boat to St Martin’s, Tresco, Bryher, and St Agnes. On each island, runners will complete a full circumnavigation before high-fiving Wez and retracing their steps in the opposite direction for a second loop. The challenge concludes with a final loop of St Mary’s to complete the full 110 km. The final island also has a cut off based on the 7:30/km so make sure you have something left in the tank!

Every athlete will experience every view, in every direction, from every stretch of coast path on every inhabited island.

This is more than an ultra — it’s a journey!

Cut-Offs & Pace

Cut-off times are based on maintaining:
7:30 min/km (12 min/mile)

Steady, unrelenting progress is essential. Pace, planning, and grit will determine who reaches the finish.
