April is earlier than usual to put on hiking boots
and tackle the national Three Peaks Challenge - but that is what one group of eight walkers did for charity.
The team were walking for the Cystic Fibrosis Trust in memory of Tonia Rivett from Dereham in Norfolk, who died of the condition last year, the Eastern Daily Press reports.
Group member Jay Eastoe-Smith noted that the weather was fine in Scotland - but that lulled the group into thinking the challenge would be easier going than it was.
He said: "We all underestimated it to be honest. The first day was nice because while we were going up Ben Nevis it was nice, clear and beautiful."
But on Snowdon, the group encountered snow, hail and rain.
Preparations included Tonia's cousin Mark - who had not previously climbed any of the mountains - receiving advice from an experienced walker at his workplace in Manchester to be careful on the summit plateau of Ben Nevis.
Walkers can easily step on cornices and fall into gullies or down the cliffs of the North Face.
