Half Marathons Found In Milton Keynes

The most comprehensive list of half marathons in and near Milton Keynes in 2026 - 2027. Find your perfect race!

MK's Redway network covers over 200 miles of traffic-free paths, and that means for half marathon training you can run for 13 miles without stopping at a junction. The network is flat throughout, which makes it good for pace work at any point in a training block. Willen Lake sits on the network and gives you a contained lakeside option, while the Grand Union Canal towpath adds more distance heading out into the countryside. Build up with 10K runs in Milton Keynes before committing to the full half.

Have a browse through the listings below. Campbell Park and Ouzel Valley Park are both on the Redways and give you open parkland and more green space within the network, which varies the surfaces you're running on. Marathons in Milton Keynes are there when you're ready to go further.
