FLATOUT London 2027
FLATOUT returns to Old Billingsgate in London for two race days on Friday 12 and Saturday 13 February 2027. The venue is a Grade II listed Victorian market hall on Lower Thames Street beside the River Thames and close to Tower Bridge.
The event uses a single timed course that runs the length of the hall. The course combines running sections with eight functional workout zones and finishes beneath the hall's iron and glass roof, including a climb to the finish. The running portion is 4 km with the workout zones integrated on the same timed loop.
Seven racing formats are available on both days, and participants choose their day at checkout. Formats listed for the event are SOLO, ELITE, DOUBLES, ELITE DOUBLES, RELAY, NEXTGEN and SIDEKICKS. The Elite Doubles format requires both participants to wear weighted vests of 3 kg for women and 5 kg for men. NEXTGEN is a junior division with adapted distances and loadings. RELAY teams consist of four participants and SIDEKICKS pair one adult with one junior.
Published entry prices vary by format, for example SOLO £99, ELITE £125, DOUBLES £199 and RELAY £295. Spectator tickets are priced separately with adults £4, under 12s £2 and under 2s free. Optional upgrades include a FLATOUT+ VIP package for an additional £15 with priority registration and bag drop plus a 15 minute massage, and a 5% defer option to move an entry to a future event within two years when requested at least 48 hours before the event. A transaction fee is added at checkout. Visit the organization's website for the most recent information.
