Wikipedia explains this better than I can:

• National Three Peaks Challenge is a mountain endurance challenge in Great Britain in which participants attempt to climb the highest peaks of each of the island’s three countries. Whilst the challenge has no official rules ot time restrictions, many participants try and complete it within 24 hours, or more leisurely over a weekend, using motorised transport to travel between the mountains.

  The mountains climbed, in order of elevation, are Ben Nevis in Western Scotland (1344 m), Snowdon in North Wales (1085 m), and Scafell Pike in North-Western England (978 m). In all the challenge involves some 26 miles of ascent and descent, with total travel approaching 500 miles. The challenge is usually undertaken starting with Ben Nevis, the highest, and for many the most distant.

Just to re-iterate:

• Three Mountains
  
• Three Countries
  
• 24 hours
