A serene park scene with a winding gravel path through tall trees with yellowing leaves, indicating autumn. Sunlight filters through the branches, casting dappled shadows on the grass. Bright green foliage contrasts with the warm autumn hues. A sunlight-dappled path winds through a serene park lined with trees in autumn. Leaves in shades of green, yellow, and orange create a colorful canopy. The clear blue sky adds to the tranquil, vibrant scene. The photo captures vivid autumn foliage with red, orange, and yellow leaves on the trees, set against a bright blue sky. Some green pine needles are also visible, contrasting with the warm colors of the leaves. The perspective is looking straight up. A sunlit pathway in a park lined with tall trees. The sun's rays filter through the branches, casting long shadows on the leaf-covered ground. The trees, with sparse leaves, indicate a late autumn day under a clear blue sky. A view looking up at a large tree with gnarled and twisting branches. The tree's leaves are a mix of green and yellow, indicating a change of season. The sky in the background is clear and bright blue, and another tree partially frames the right side of the image.

Prize Categories
There is no on the day prize giving because of the multi wave, multi start time format of the events.

Prize winners
will be contacted by the end of race week.
The final number of prizes awarded is determined by the number of finishers for each gender in a given race distance. If there are more than 100 finishers then the full range of awards are made (top 3 along with first in each age group). If there are between 50-100 finishers then the top 3 finishers overall will be awarded a prize. If there are less than 50 then only the winner will be awarded a prize. We do not have any winner's prizes for any of the children's events as we would like to keep this participation focused
