Haywards Heath, Burgess Hill and East Grinstead, and the villages from Copthorne to Hassocks.

Training in Mid Sussex

Three commuter towns with a public centre each, and one of the most active populations in the South East.

Mid Sussex had around 152,600 people at the 2021 Census, up 9.1% since 2011, with a median age of 43. Its three towns are Haywards Heath, Burgess Hill and East Grinstead, and it runs from the High Weald, taking in part of Ashdown Forest, down to the South Downs National Park. It's one of the most active parts of the region: in Sport England's Active Lives survey for Nov 2024–25, 70.9% of adults did at least 150 minutes of activity a week, against 67.4% for the South East and 64.6% for England.

Places Leisure runs the council's three leisure centres: The Triangle in Burgess Hill, with flumes, an outdoor lido, climbing walls, squash and padel; The Dolphin in Haywards Heath; and the Kings Centre in East Grinstead. Freedom Leisure runs Hassocks Sports Centre, David Lloyd has a club at Wickwoods near Albourne, and there's PureGym in all three towns.

Beyond them are CrossFit boxes near Cuckfield and at Copthorne, jiu-jitsu and MMA in Haywards Heath and East Grinstead, and old railway paths out of East Grinstead. Wherever you train, it's easier with the right company. Gymist is how you find them.
