Royal Navy aircrewman begins Devon to Land's End (DEVLE) marathon Royal Navy aircrewman Liam Armstrong from Royal Naval Air Station (RNAS) Culdrose has begun his North Cornwall Coastal Marathon Challenge in aid of The Royal Navy and Royal Marines Charity and Bliss. His mammoth run will see him cover the entire length of Cornwall's Northern Coastline from Hartland Point in Devon all the way to Lands End at Cornwall’s South Western tip - a route commonly referred to as the DEVLE run. Liam is raring to go and is looking to smash the current record of 40 hours and 56 minutes by more than 5 hours. Keeping to a very strict schedule Liam set off at 10pm on Tuesday 27 January. Challenging conditions Liam (28) from County Durham is attempting to break the record for running non-stop from Marsland Mouth near Harland Point all the way to Land’s End, a distance of 144 miles. The ‘At Your Pace: North Coast Challenge’, as it is formally known, will be made even more challenging by the wintery weather and very strong head winds, forecast to be in excess of 30 Miles per hour over the course or the coming days. "I’ve put the training miles in for this challenge,” said Liam who is currently an aircrewman trainee on the new Merlin Mk2 helicopter with RNAS Culdrose’s 824 Naval Air Squadron. "All I need to worry about now is making sure I’m mentally focussed on crossing that finishing line at Land’s End.” Liam has already raised half of the £1,440 he expects to make over his fundraising challenge, that’s £10 per mile for his two chosen charities: The Royal Navy and Royal Marines Charity and Bliss, a charity which supports premature babies and their parents in their time of need. Liam and his wife Kate are expecting their first child any day now. Liam is upbeat and unfazed by the challenge ahead: “I just want to get started and set off on the route. Once start all I have to worry about is the track, my trainers and keeping hydrated. It’s going to be hard and exhausting but I think I’m ready for anything.” You can donated to Liam's challenge at http://uk.virginmoneygiving.com/DEVLErun The route Liam’s DEVLE run started at 10pm on Tuesday 27 January near Hartland Point (Marsland Mouth).
