Bike and Run Time Trial (BaRTT)

Sign up

The BaRTT series is very popular with members of all abilities and sign-up is recommended in the Event calendar to guarantee a place, although we will accept entries on the day on a first come - first served basis. To ensure the event runs smoothly, and to minimise disruption to local residents, we limit the number of people taking part to 30. If you sign up but are then no longer able to take part, please ensure that you cancel your sign up so that another member can take your place.

Sign up opens 1 week before the session and closes at midnight the night before the event so that the start list can be drawn up by the volunteer time keepers. 


Parking, changing and toilet facilities at Oxsrad Sports Centre, Marsh Lane, Marston OX3 0NQ. Transition is across the road in Horseman Close, OX3 0NR. Please do not try and park in Horseman Close - all parking is over the road at Oxsrad. There is a path out of the far corner of Oxsrad carpark that comes out directly opposite Horseman Close by the pelican crossing.

Results and Season Long Tracking

Results will be published on Facebook and the website after the event has been run.

This is a great way to monitor your progress over the course of the season, it will help track you performance and motivate you over the coming season of BaRTTs.

We will as usual run a series scoring system based on your best five results over the summer. The top 8 finishers in each category (Senior Male, Senior Female, Vet Male, Vet Female, Super Vet Male, Super Vet Female) will get 10, 8, 6, 5, 4, 3, 2, 1 points respectively for each event. There must be at least three people in your category for the result to count. We would ask that everyone who competes regularly volunteers for time keeping at least once in order to qualify for the series scoring.

There is also a handicap final event. This takes a slightly different format with the time intervals calculated in a cunning and scientific manerr with a prize for the first athlete to cross the finishing time. To qualify for the handicap final you will need to have taken part in at least 2 events through the season.
