PHOENIX - Five in Five Run Series 2027

Immerse yourself in the vibrant energy of the Thames Path for the 2027 Easter Five in Five (FiFi) race series, an exhilarating multi-day running challenge that promises excitement and camaraderie. As part of our annual ten-in-ten and twelve-in-twelve events, this five-day extravaganza returns to Walton on Thames with a range of distances designed for runners at every level.
Each day from April 7th through the 11th, participants can choose between 5km, 10k, half marathon, full marathon, or ultra-distance runs along our certified and measured routes. The race loop follows the picturesque River Thames on an out-and-back course that offers stunning views and a serene setting for runners to push their limits.
The FiFi series is structured around timed events lasting up to five hours per day, though early morning starts at 6:15 AM allow ambitious athletes nearly nine hours of running time. Whether you're looking to build endurance or simply enjoy the scenic route, this event caters to all abilities and goals. Completing even a single lap on any given day earns you finisher status for that session.
The Weir Pub stands at the heart of the action as both start/finish line and social hub, with plenty of local accommodations available nearby. Our legendary aid station will be back in full force this year, offering runners an array of sweet treats, savory snacks, and a generous helping of CAKE to fuel their journey.
What sets FiFi apart is its unique medal system for those who complete all five days. Each day brings a new 'Lantern' medal – Fortitude, Gauntlet, Dauntless, Resolute, Perseverance – creating a stunning collection that celebrates the spirit and perseverance of multi-day runners. Finishers can also opt to purchase specially designed FiFi finisher t-shirts in Half-Marathon, Marathon, or Ultra categories.
With limited spots available, early registration is recommended for this unforgettable experience along the Thames Path. Join us as we celebrate running culture and community during one of the UK's largest multi-stage events.
The Five in Five promises to be a highlight of your racing calendar – an opportunity to challenge yourself amidst breathtaking scenery and warm camaraderie.
