The Phoenix Hydra is a 75 mile ultra run held at Denbies Wine Estate in Dorking, Surrey. The main ultra uses a single one mile loop on off-road trails around the estate. The loop is described as flat-ish with slight inclines and cambers.

The event is fully chip timed and includes an aid station described as well stocked. Organisers state they aim to provide a safe, inclusive and friendly environment for runners. Entry places are limited. Participants, whether attended or virtual, receive a physical giveaway medal or memento for their run.
