The Olympic spirit could resurface this weekend as a wacky “school” sports day for adults takes over the borough’s biggest park.

Grown-ups will get the chance to relive the carefree fun of the sports day by entering the Oxlympics at Highbury Fields on Sunday.

The contest will see teams tackle a host of athletic challenges – though organisers admit some of the more outlandish events may not have occurred at too many schools.

They include welly wanging, which involves hurling wellington boots, slug racing, much like a sack race as the competitors attempt to sprint while wearing sleeping bags, and the Zoolander walk-off, inspired by a scene in the Ben Stiller movie.

Organiser Nishaan Saccaram, 33, said: “We want to recapture the excitement of school sports days. The Olympics has been really great at capturing the nation’s spirits, but we also want to reflect the fact that sport is fun.

“It’s not about training seven hours a day to shave two tenths of a second off your best time. It’s not just about competition and performance, it’s about taking part.”

The Oxlympics is being hosted in aid of Oxfam Islington, to raise money for the charity’s fight against poverty. Teams of up to eight are urged to get involved, with a �3 fee per person.

Mr Saccaram added: “We wanted to do something a bit different to the usual fundraisers and thought it would be great to have a big adults sports day where people can relive their old times.

“We want to remind people that exercise can be fun.”

The sports day is part of a series of events building towards the Oxjam Islington festival, which will see venues across the borough host live music fundraisers on Saturday, October 13.

Alongside the event at Highbury Fields on Sunday there will also be music, stalls, workshops and free family-friendly activities.
