Formula fun: Runners rev up for annual F1 track treat

Most people spend New Year's Day enjoying a relaxing meal at home with family - not so the 10,000 hardy souls who will instead get the blood pumping by running around a Formula One track.

On Tuesday, the fifth edition of the Run the Track half marathon will be held at Shanghai International Circuit, home of F1's Chinese Grand Prix.

Since its debut in 2015, the race has become a popular New Year's Day activity in the city, with places in the race a coveted commodity.
