DOSE Challenge

This month breath in the pure crisp air of the outdoors with our new challenge and feel those serotonin levels soar! Heading outside is scientifically proven to trigger the release of serotonin, that feel good brain transmitter. As you soak in your surroundings, you get a surge of positivity that uplifts your mood and fosters a sense of wellbeing and serenity. 

Join us by taking the indoors, outdoors with a FREE Exercise Class!  

In honour of Serotonin and the beauty of nature we are thrilled to invite you to join a complimentary Leisure World Group Exercise Class at Castle Park! Let’s shake up our daily routines, by embracing nature and nourishing our mind, body and soul with others in a historic Castle Park. Listen to the sounds of the birds, get those bodies moving and those serotonin levels soaring. Come and be a part of it! 

Class Dates:



Every participant will automatically be included in a prize draw for a chance to win a small plant or shrub courtesy of the Community team at Colchester City Council. It’s our way of enhancing your gardens and outdoor spaces, ensuring they remain tranquil and contribute to sustaining that blissful Serotonin boost!
