Entries open on Friday for the Lowe Alpine Mountain Marathon, which bills itself as the connoisseurs’ marathon.

As usual, there’s no indication of the actual site of the event, other than the cryptic hint that it will take place two hours’ drive north of Edinburgh and Glasgow and 2¾ hours from Aberdeen.

So get your maps and calculators out and try to figure where the race will take place. Suppose it depends how fast you drive!

Booking for the marathon, which takes place on 9 and 10 June, is online, where you’ll also find details of last year’s Assynt event and those from Mull and Glencarron in the preceding races.

Teams of two make up the entries for the LAMM, which is a test of mountain navigation as well as fitness. Check out the website for details of how to apply.

If a two-day event is a bit beyond your capabilities, there’s the Wuthering Hike, a 31-miler on the moorland between Haworth and Todmorden in West Yorkshire.

The Hike is part fell race, part walk – depending on your preference – and is open to both solo runners or walkers and pairs. Winning time last year 3h 46mins, but if you’re a walker, you’re allowed 12 hours to complete the course.

The Hike takes place on 10 March and is the first event of the Montrail Ultra Running Championships, a series of 12 races ranging from the 26-mile Pumlumon Challenge in mid-Wales to the daddy of the long-distance events, the Fellsman Hike, a 62-miler crossing many of the Yorkshire Dales’ top peaks.

Wuthering Hike details are on the Keighley and Craven Athletic Club site and the Montrail Ultra Running site can be found here.
