A Munro is a mountain in Scotland with a height over 3,000 ft (914.4 m). They are named after Sir Hugh Munro, 4th Baronet (1856–1919), who produced the first list of such hills, known as Munros Tables, in 1891. A Munro top is a summit over 3,000 ft which is not regarded as a separate mountain. There are 282 Munros and 227 further subsidiary tops. The most well known Munro is Ben Nevis, the highest mountain in the British Isles, with an altitude of 1,344 metres (4,409 ft).
The Munros of Scotland are known for presenting challenging conditions to hikers, particularly in winter when a number of fatalities are reported each year. Nevertheless, a popular practice amongst hillwalkers is "Munro Bagging", the aim being to climb all of the listed Munros. As of 2009 more than 4,000 have reported completing their round. The first continuous round of the Munros was completed by Hamish Brown in 1974, whilst the current holder of the record for the fastest continuous round is Stephen Pyke who completed his 2010 round in just under 40 days.
