About Us

OSB Events is one of the leading sporting events companies in the UK. Since organising our first event in 1991, we have hosted hundreds of events for thousands of competitors in and around the Midlands. Iain Hamilton founded OSB Events as a college project 25 years ago - he won a lifetime achievement award in 2015 for his work developing the sport in the UK.

As organisers of the award winning Outlaw Triathlon, Triathlon Relays and the now infamous Saucony Cambridge Half Marathon, we take a huge amount of pride in our events, with customer satisfaction at the forefront of everything we do. We are athletes ourselves and aim to think of everything from the participant’s perspective in order to deliver a safe, enjoyable and memorable race experience - races that we'd like to take part in ourselves.

Our Events

As a family-run, full time and experienced event management company, we apply the exact same event formula and staff team at all of our events, from the biggest to the smallest, so you can enter with confidence that you'll have an enjoyable and safe race experience.

Our marshals are an invaluable part of our team; some of them have been with us from the very start! We like to think this is because we’re one big family, and we welcome marshals and competitors alike with open arms. If you have any worries or questions during your event, don’t be afraid to ask!
