OSB Events is a multi award-winning sporting events company. Since organising our first event in 1991, we have hosted hundreds of events for thousands of competitors in mass participation endurance sports. Iain Hamilton founded OSB Events as a college project and has built a business employing a dedicated work force. 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 Series and the Cambridge Half Marathon, we take a huge amount of pride in our events, with customer satisfaction at the forefront of everything we do. We have been, or still are athletes ourselves and aim to look at 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.
As a full time, 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 regular event crew is 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 crew members and competitors alike with open arms. If you have any worries or questions during your event, please just ask us!
