Race Info
The Helsinki City Double combines the full marathon and the half marathon on the same Saturday, 63.3 km in all. Runners complete the two-lap marathon, finish in the Olympic Stadium, then walk about 400 meters to the half marathon start on Mäntymäentie and run that course as well. Both distances are scored on their own, with a combined Double result and a separate Double medal.
