2026 Chelmsford Marathon - Oct 11

Single-lap road course, start and finish in Central Park marathon course in Chelmsford with 180m elevation gain. A gently undulating road marathon rather than a flat or a hilly one. The single lap opens on the tree-lined avenues of Central Park, then heads out onto rolling rural Essex country lanes before returning to the park to finish. There are no major climbs, but the steady rises mean it is not a dead-flat PB track
