The Jenner Jog begins at the Jenner Museum in Berkeley town centre, the birthplace of vaccination, and offers participants a chip-timed 10k road race. It is UK Athletics measured and Power of 10 licensed, suitable for runners seeking an official result and those wanting a simple local 10k.
The course is mostly flat, incorporating country lanes and the centre of Berkeley, with a loop and an additional out-and-back turnaround. New Berkeley Harriers organize the event. Finishers receive a bespoke medal, water is available at the halfway point and the finish, and the Jenner Museum provides refreshments post-race. Local support contributes to the atmosphere, and the open-road nature of the race dictates the rules: no running buggies, no standard headphones, and an entry age minimum of 15.
