The downhill racecourse being steep and slippery makes cheese rolling difficult. This terrain can make it challenging for participants to maintain their balance and control their speed as they chase after the rolling wheel of cheese. Additionally, the short and muddy course adds another layer of difficulty by creating uneven footing and obstacles that can trip up racers. The heavy and hard-to-move wheels of cheese only add to the challenge, requiring participants to exert extra effort to keep up with them. Overall, these factors combine to make cheese rolling a physically demanding and tough event.
