The Boat Race: Cambridge v Oxford in crazy golf challenge

Cambridge and Oxford go head to head in a special dinosaur crazy golf challenge ahead of this Sunday's Boat Race.

BBC Sport's Clare Balding presents the competition with George Nash representing Cambridge and Constantine Louloudis taking part for Oxford's crew.

The duo are no strangers to high-profile rowing competitions having won Olympic bronze medals at London 2012 - Nash in the men's pair and Louloudis in the men's eight.

Watch The Boat Race live BBC One from 15.15 BST on Sunday 31 March.
