Collis Birmingham just loves running.
While many international track runners have spent the past month taking a well-earned rest and putting their feet up in readiness for another gruelling winter of training, the 28-year-old has swapped his spikes for racing flats, choosing to return to the half-marathon distance at British races in the autumn.
It has been a long season for the Australian, whose season began in January and has never really ended, having raced in every calendar month since then.
At the start of the year he set an Oceania record of 1:00:56 at the Marugame Half Marathon in Japan in February. His most recent effort was a fourth-place finish at the Great Birmingham Run on Sunday (20) and his 1:03:44 clocking on a tough course was an improved performance after a slightly disappointing run at the Great North Run in September.
