The Big Half 2026
A big-city half from the London Marathon team: Tower Bridge, the Highway, and a finish by the Cutty Sark, from £15.
1 weeks to race day: the sharpening window
A full build no longer fits, but a sharp one does. This close in, the job is specificity and freshness: race-pace touches, open-water or brick rehearsal, and a taper your nervous system actually absorbs. No heroics; arrive fresh.
Building for this one? Training plans cover the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.

Commit to the date and we will walk you to it: a countdown, honest guidance by email, and the debrief afterwards. Full adaptive training for running races is coming; nothing here pretends otherwise.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“London Marathon's little sibling and the perfect dress rehearsal: same organisers, same energy, a third of the distance.”
The race
The course
No course maps for this race. The organiser publishes no downloadable route for any leg of this race, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Point to point across London: start on Tower Bridge, finish beside the Cutty Sark in Greenwich. First run in 2018 and organised by the London Marathon team, which is why the closed roads and the crowd feel like a scaled-down version of the marathon itself. The weekend also carries the Big Relay and the Big Mile.
Not yet confirmed for this edition: detailed route, elevation gain, cut-off times, start time. We publish these only once they are on the official course page, so check there before you pace off anything here.
Course details verified against the official The Big Half course page on 14 August 2026. Courses change; the official page is always the last word.
