Runners in red will dominate Canary Wharf for The British Heart Foundation’s annual event.
A mass warm-up in Canada Square Park will kick-start the Canary Wharf Jog on June 17, where competitors can tackle as many 1km laps as they fancy - up to a maximum of 10.
Fancy dress is optional for those pounding the pavements in North and South colonnades against a backdrop of the estate’s gleaming towers.
Entry is free with money raised pumped into the charity’s life-saving research into heart disease.
