Winter BallbusterThe 2016 CEP BallBuster duathlon is scheduled to take place on Saturday 12 November at its traditional home of Box Hill, Surrey. Since debuting in 1990, this gruelling event has maintained its reputation as an extreme test of endurance, with competitors asked to cover 40 miles in one morning. Entries are now live, but with the event regularly selling out early, best register soon.

The challenge starts with an eight mile undulating run taking in the scenery around the National Trust site. Once they have returned to the top, it’s into transition for the cycle leg which comprises three laps of the same eight mile route. There’s a final eight mile lap on foot before crossing the finish line.

The BallBuster has been running since December 1990, when it was one of the very first events conceived by organisers Human Race. Last year Andy Greenleaf smashed the course record, being the fastest person in the long history of the event, finishing in 2 hours, 31 minutes and 54 seconds.
