Andover Half Marathon & 12 km

The Andover Half Marathon & 12 km takes place on 25 October 2026 in Test Valley, in the United Kingdom, whose main town is Andover. Two road races are on the programme: the 21.1 km half marathon sets off at 8am, followed by the 12 km at 9am. No elevation figures have been published for either distance.

The hour between the two starts lets you choose according to how much you want to take on. The 12 km is a handy in-between distance: tougher than a 10K, it can be prepared without the volume a half requires and suits anyone wanting to test their threshold pace in a race. The half marathon calls for a weekly long run gradually built up to 16 or 18 km over the two months beforehand. A morning start at the end of October means a longer warm-up than usual and layers you can shed before the gun.
