The London leg of the nationwide Comms Charity Go-Karting challenge led by Chess in support of the Prince's Trust and Sparks culminated with Chess Chief Exec David Pollock being named Champion, beating Simon Tompkins of Jaguar Telecoms into second place while Chess Partner Services' Joe Green completed the podium.
Pollock said: "I'm slightly embarrassed about hosting and winning the event but my competitive personality got the better of me.
"It was great fun, loads of laughs and testosterone in full flow, everyone had fun. CSR is in the heart of our business and we believe that part of our success is to give something back to the community.
"There's a sense of enjoyment, pride and participations in helping those less fortunate than ourselves and this event was a great example of that."
Sponsors included TalkTalk Business, Chess, eBillz and Comms Dealer. The event raised a total of £6,600.
eBillz MD Arvind Meghani enthused: "We had such a fantastic time. The event was well planned, well run and the race was good fun. Most significantly, we have raised some money for some great charities."
Chess raised over £48,000 for charities in 2013 and is on track to beat that this year.
