Competition is nothing new to Clarksons brokers, but for one day only this Tuesday their main rivals will be their colleagues.

Around 250 staff from the world’s largest shipbroker are going head-to-head for a good cause in a team HIIT class competition, which is akin to circuit training.

The Clarksons Playoffs, a fitness challenge involving teams from offices around the world, is being organised as part of the London Lord Mayor’s City Giving Day.

It is described as an intense fitness challenge with six exercises over six minutes, with 45 seconds of workout time and a 15 second breather while moving to the next station.

The teams are scored by the number of sets they can complete in the allocated time.

With a young kickboxing champion and a number of talented football and rugby players spread among the teams, it is expected to be keenly contested.

The competition kicks off at 11:30 British Summer Time on 25 September and will last for seven and a half hours. Click here to follow the action or make a donation.

Company charity Carney’s Community, which aims to get disadvantaged and excluded young people off the street and away from a life of crime and despair, will be participating at the London office.

Each team has also chosen a charity which holds personal relevance to raise funds for.

The exercises have been put together in partnership with F45, the London fitness company, and with unprecedented numbers taking part it is expected a record fundraising total can also be reached. Last year £41,000 was raised for various charities.

Starting with a children’s charity bake sale on 30 August in aid of the First Love Foundation this year, Clarksons is raising money for 17 selected charities.

The Clarksons Charity Giving Day began in 2015 after the tragic loss of specialised products broker Roger Pyatt, who suffered a sudden heart attack as a result of a peripheral Arterial Disease.

The first event was given the name “Row for Roger”, with participants undertaking a rowing challenge to beat a containership transiting the Panama Canal. It raised over £20,000.

Clarksons expressed its thanks to its friends across the industry for their support.
