Hello, tomorrow I was planning on doing the three peaks by rail challenge. We start with Snowdonia at 21:30. Temperatures at this time are still quite high and I feel as though it is a bit unsafe to do in this weather. I love hiking but I am only a beginner and have never hiked in hot weather (let alone a heatwave), does anyone with a bit more experience think it would be wise to back out of this? Thanks :)
