Yorkshire Three Peaks - Is it suitable for me? The Yorkshire Three Peaks Challenge is demanding and requires a good level of fitness & commitment and you must be able to walk for up to 12-hours over hilly terrain. It’s harder than the Edale Skyline Challenge but easier than the National Three Peaks Challenge. There are a few places where it’s possible to drop out safely & there are opportunities en-route to buy refreshments, including hot drinks, and to re-fill water. It's very achievable for anyone willing to comit to a training plan and with a positive & flexible mindset.
