About
A vibrant, inclusive half marathon that celebrates the diversity of London, running through four boroughs — Tower Hamlets, Southwark, Lewisham and Greenwich — from Tower Bridge to Cutty Sark.
Catering & aid stations
Water (Buxton mineral water) and Lucozade Sport available at miles 3, 6, 9, and 11; toilets and accessible facilities at start, finish, and miles 3, 6, 8, 11; energy gels and fruit at aid stations; no beef served in 2024 food offerings due to carbon reduction.
Pacers
Pacemakers will be present on race day with colour-coded vests showing their target finish time. They are positioned in specific start waves to help runners maintain a steady pace — look for the flag on their back matching your finish time. Pacers provide a supportive, steady-pace option for runners of various abilities, and their presence is confirmed on the event day schedule.
