Harrold-Odell Country Park - 25km & 50km Trail Races

Sat 7th March 2026

A group of runners in athletic gear approach the finish line during a race. They are outdoors on a grassy field beneath an archway that reads "FINISH." The sky is clear and trees are visible in the background. A person in a blue running vest triumphantly crosses a race finish line with arms outstretched. Other runners and spectators are visible in the background, on a grassy area with trees. The sun casts shadows on the ground. A person wearing a black athletic outfit and cap smiles and holds a medal and a can. They have a race number on their shirt and are outside on a sunny day with a green field in the background. A table displays numerous silver medals with yellow ribbons. Each medal features a blue and green graphic and the text "SOKM" on the ribbon. They are arranged in straight rows under bright lighting. A white flag with the logo for "Thunder Races." The logo features a mountain, trees, and birds with the tagline "Where the Adventure Begins." The flag is outdoors, with green grass and a blurred background. A tranquil river scene with a lush canopy of overhanging trees. A small building with a slanted roof is partially visible among the greenery. The water reflects the surrounding vegetation under a cloudy sky. A scenic landscape with a wide field featuring a dirt path leading through grassy terrain. Trees border the field under an expansive, cloudy sky. The setting is tranquil and open. A narrow, moss-covered wooden plank bridge crosses a small ditch in a lush, green woodland. The bridge connects to a path leading through dense foliage with large trees and leafy undergrowth. Sunlight filters through the leaves. A tranquil forest scene with a dirt path covered in fallen leaves. Tall trees with lush green foliage arch over the pathway, creating a peaceful, shaded canopy. The ground is dotted with patches of green undergrowth, adding to the serene atmosphere. A grassy path extends through a rural landscape, flanked by dense green hedges and a large, leafy tree on the left. The sky above is filled with gray clouds, suggesting an overcast day. Fields and distant trees are visible in the background.

Great event which was organised. Although I thought the add stations could have been spaced out more evenly, which I understand can be a logical nightmare on trail runs. Signage was good, although got a little confusing where the route touch in places. Would I recommend this event, most definitely.
Thanks for the review Peter. It was great to have you with us 👍
