JESSIE J has been announced as the headliner for today’s Run to the Beat half marathon in Greenwich.

If the 19,000 runners have enough energy after completing the 13.1 mile course they can dance along as the popstar plays an hour long set in Greenwich Park.

Her set starts on the main stage in the spectator area at 12.30pm to ensure the party atmosphere continues well past the finish line.

Run to the Beat includes music as the competitors pound the pavements of the route.

This year DJ talent includes Radio One DJ Nihal, Beckenham’s Kerrang! Radio DJ Kate Lawler, DJ Goldierocks and acid house DJ Trevor Fung.
