He's by far the oldest in the field, but Prince Philip will be hoping that age and experience will carry him to a long-awaited victory at the Alnwick Castle Horse Driving Trials.
Having turned 85 in June, the senior royal is showing no sign of slowing down at the prestigious contest, which started in the Pastures yesterday.
The Duke of Edinburgh got off to a flying start by taking first place in the driven dressage class, steering the Queen's fell pony team in the opening stage of the three-day competition.
But the prince will face his toughest challenges today and tomorrow.
The first is the gruelling 22km cross-country course, which involves navigating a highly technical obstacle course spread over four kilometres at full gallop.
And tomorrow he faces the cone driving, which will test his experience to the limits. Prince Philip was pipped to the top spot by a few points in recent years and now reportedly has a burning desire to finish first.
The event also includes a funfair, vintage cars, falconry, terrier racing, stunt bikes, dog agility, pony rides and the usual arts and crafts stalls.
It is open from 9am-4pm today. Entry costs £7 for adults, £1 for children and parking is free.
