Grab your oars, get your ‘heave' mantra at the ready and feel the burn as this exhilarating challenge will have you tutting at the weak efforts of the Oxford and Cambridge boat race. Steely-eyed stares, clenching of jaws and bracing of shoulders will turn you from laid-back weekend tripper into fierce oarsmen and women. Or will you just become gasping giggling wrecks, nearly capsizing the whole crew and realizing that you have no rhythm or strength at all. Anyone for a massage?
