View all ↓Spring 2026 Marathons
There are loads of other options for great Spring Marathons in the UK. If you intend to follow a traditional 16 week training plan then anything from late April onwards means you'll be able to enjoy Christmas and New Year before getting stuck into training in January.
Check out our full list of Spring 2026 Marathons below, and if you are looking that big city atmosphere then check out our curated list of late-spring big-city marathons on our London Marathon Alternatives page - there are some crackers, especially if you don't mind a trip to the continent for your race.
