Pack this
- Two 500ml bottles + electrolyte drink mix for pre-race hydration
- Energy gels or chews (6–8) for miles 8–35, test during training
- Moisture-wicking long-sleeve shirt and shorts with pockets
- Lightweight windproof jacket or gilet for cool conditions

What you should know
- Miles 20–24 have gradual rises towards Tower Bridge; manage pace and fuel accordingly on the tougher section.
- Drink stations are roughly every 1–2 miles; plan hydration to avoid over-drinking and dehydration in 12°C.
- Cool conditions let you stay warm while running but heat loss quickens after finishing; bring dry kit for the finish.
- The course has a ~6.5-hour cutoff; confirm your target finish time before the road reopens.
- Bib pickup at the Expo is mandatory 3–4 days before race day; collect early to avoid queues.
- Headphones are not permitted on closed-road sections; rely on drink stations and crowd support.
