With the days getting lighter and longer, the time is approaching when many people will take on the Three Peaks Challenge for charity.
Taking on Ben Nevis, Scafell Pike or Snowdon is no stroll in the park, so to do all three inside 24 hours is a major undertaking, one that only fit and well-equipped walkers are likely to be able to manage.
Ben Nevis is a long, hard climb and may surprise those inexperienced in Scottish conditions with the snow patches on its summit in summer, Scafell Pike is a very steep and rough climb and while the route up Snowdon is likely to be among the easier ones, it is still a long hike for those with tired legs and blisters.
Among the teams taking on whatever the mountains can throw at them is a group of young ladies who work in High Wycombe in Buckinghamshire, the Bucks Free Press reports.
Their motivation for the climb is to raise funds for the British Heart Foundation, with all the members of the team from electronic components firm TTI having lost relatives to heart attacks.
All kinds of charitable reasons may tempt people to put on their walking boots
, but they need to ensure they are well equipped with waterproofs
, outdoor jackets, Ordnance Survey maps
and torches for the darker parts of the walk.
The last aspect may be considered superfluous in June's very light hours, but anyone who has spent an evening in Glen Nevis around that time of year will have seen a steady stream of lights as the last stragglers come down from Ben Nevis - often those who are struggling the most.
Of course, there are always some exceptions to the rule. Last week, the Wells Journal reported that a team from the town's Rotary Club will be taking on the challenge with some of the members opting to sport kilts as they take the path up Ben Nevis.
Some people like this kind of thing: Jolene Clark of Dundee went one further in 2010 when she decided to climb Ben Nevis in a Bikini – the first person brave (or mad) enough to do so.
While such feats may be impressive, most will find that climbing these mountains safely is quite enough.
