Clarksons' brokers HIIT the jackpot at the company’s annual charity day, raising £80,000 ($104,000) for good causes.
The figure was double the sum raised in 2017, with this year’s event attracting more than 200 participants to circuit training-style competition.
Clarksons devised the event in partnership with London fitness company F45.
Teams completed six exercises over six minutes, with 45 seconds of workout time and a 15-second breather while moving to the next station.
