Tipped as one of Great Britain's contenders for a medal in 2012, German-born Bechtolsheimer has been riding since the age of three and turned her attention to dressage at 13.
She burst onto the scene in 2005 when she became the youngest British dressage champion aged just 20, riding Douglas Dorsey.
Bechtolsheimer went on to compete at the 2008 Olympics in Beijing aboard her favoured horse Mistral Hojris, gaining 18th place in the Individual Grand Prix Special and 6th place in the team event.
Her first real career high came in 2009 at the European Championships when team GB took silver and Bechtolsheimer the individual bronze.
Further success followed at the 2010 World Equestrian Games held in Kentucky, USA, where the rider walked away with team, individual and freestyle silver medals having surpassed her personal best scores.
Together Bechtolsheimer and Mistral Hojris now hold the British international grand prix record in all three classes - the grand prix, the grand prix special and the grand prix freestyle.
Following her success last year in Kentucky, the dressage expert is a favourite for Olympic success in front of a home crowd in London.
