Whether it’s your first time tackling the half, or you’re a seasoned veteran warming up for a full marathon – a UK Half Marathon is a worthy challenge. Running a half marathon isn’t easy, but here at Run Through UK, we know you’re going to be hooked (or already are hooked!). For every runner, a half marathon should be on their bucket list – or at least a stepping stone on the way to a full marathon.

Half Marathon UK’s Premiere Running Event Organiser

As one of the UK’s best half marathon event organisers, we’re well prepared to give you a seamless, brilliant experience. All of the events you’ll find in our calendar are our own organised running events – we don’t sell places to other organisers’ half marathons.

This is so we can ensure you know what you’re getting when you run with us. We’ve worked hard to bring you a great range of running events around London and all through the UK. Whether you’re an experienced runner, a fitness enthusiast or just getting started, you’ll find yourself challenged and supported.
