Half marathons are an ideal fitness challenge. Not as gruelling as a full marathon and more testing than a 10k, they're the perfect middle ground to test your fitness and endurance.
They're also a great opportunity for a runcation - i.e., combining a fitness goal with the reward of travel. Whether that's to Europe or further afield, or even to explore those parts of the UK you never got around to visiting.

Tips for Planning Your 2026 UK Half Marathon
- Book way in advance: Half marathons in the UK sell out fast. Secure your spot early doors and make sure you book your accommodation well in advance if you're planning to stay overnight. You don't want to overspend or find everything's fully booked a week before the run.
- Layer up: The weather here is unpredictable to say the least. Layers are the key to warming up, down or protecting yourself as much as possible from those spontaneous rain showers we all know and love.
- Sleep early, leave early: Most runs start early on Sunday morning. And with roads often cut off, especially for the run, everything is busier on run day. Adding another third onto Google Maps' predicted journey time should ensure you're not late to the start line.
Run to Victory, Not Out of Data
It's great to know you're at peak fitness and looking to achieve your running goals for 2026. But everyone knows the point of running a half marathon in the UK is to share your PB and medal pics on social media.
