Olympic legend Sir Steve Redgrave knows a thing or two about rowing challenges, and he has added his support to a marathon attempt set to take place at Monmouth Comprehensive School next month.There are few comprehensive schools in the UK which have their own boat club and can therefore offer pupils the chance to get involved in the sport of rowing � although it was at Great Marlow Secondary Modern School that Sir Steve's talent was first spotted.Monmouth Comprehensive School Boat Club offers that chance to more than 100 pupils each year, and currently has a competitive squad of more than 30 students who compete regularly at regional and national events, winning a bronze medal at the National Championships in 2004.On February 26th, each member of the club is planning to row the equivalent of an Olympic race (2,000 metres) 12 times on indoor rowing machines in a 12-hour marathon designed to raise money for both the club itself and the Steve Redgrave Trust.In addition, teachers, governors, parents, local politicians and others are being challenged to keep a 'guest' machine running for the duration of the marathon.In previous years, the boat club's marathon has raised around �100 for each person involved, giving a target of more than �3,000 in 2005 � which organisers hope will be beaten thanks to Sir Steve's support.Sir Steve said: I think it is vital that the grass roots of any sport are maintained, and members of boat clubs such as the one at Monmouth Comprehensive School are part of the future of the sport of rowing. Clubs such as this one offer the chance for all pupils, irrespective of their personal finances, to get involved in healthy sporting activity and may also unearth some sporting stars of the future.
