I am unable to generate a description for the "Baker Lake 50K" located in Wakefield, England, on October 3, 2026. My comprehensive search for this specific race name in Wakefield, England, and for ultramarathons in the region during October 2026, did not yield any relevant results.

Information regarding a "Baker Lake 50K" consistently points to a race held in Washington state, USA, near Mount Baker, and not in the United Kingdom. Therefore, I cannot provide an accurate description based on the provided race name and location.
