Thames Moonlight 10 Ultra Challenge

September 11, 2026

The Moonlight 10 Walk kicks off the famous Thames Path Challenge weekend festival of riverside events. Take on either a spirited 10 km or an energetic 10 mile looped route walk through the heart of London as darkness falls and the Moon rises.

Experience London in a different light, passing famous landmarks – including St Paul’s, Westminster Abbey, Tower Bridge, the London Eye and more. A lively finish line awaits – with a glass of fizz & a special Moon medal – followed by some welcome hot food & drink.
