There could be a temporary change of workout attire in Canary Wharf after Virgin Active offered free use of its facilities to those dressing up for the Virgin Money London Marathon .

Colourful runners will be able to access the gym floor at any Virgin Active UK gym to test out their cardio and core strength the week before the race on Sunday, April 24.

Virgin Active’s Andy Birch said: “Finishing the marathon is an amazing achievement in itself, however those runners who accomplish this feat in costume have our serious respect.

“We know how important preparation is when it comes to marathons, which is why we’re offering runners access to our gym floors anytime this week to make sure they feel ready, no matter what their attire is.”

To guarantee entrance to the gym floor, marathon runners must arrive with their costume, ID and proof of race entry, but are encouraged not to bring anything too overbearing.

Virgin, sponsors of the race, said managers reserved the right to refuse entry if the costume was a health and safety hazard on the gym floor.
