Wow, got an idea of what the event is about. Took my step son and went to walk across Bleaklow last night. Pitch black, no light not even a star to glow. Thick fog and visibility down to about 3 metres. Made nav very interesting but just about managable with map, compass and GPS but very difficult. On pennine way could cover reasonable pace, once paths were vague, slowed right down., really right down. We went across the moor and by midnight decided enough and pitched the tents. Can't imagine how eiry this will be alone and tired during the race. Coming back we could check the route this morning and some very difficult sections were just difficult because we couldn't see the right path a mere metre away.
hopefully a late start to training wont hurt, had a Achilles injury from July but have ran Helvellyn and Blencathra over the last week. Tried out the new Osprey Talon 33 and that went well. Not waterproof I expect so will be using dry bags. powered walked up with a pole and ran flats and downs.
Andy - Gps. I have tried this on a budget. Used a Etrex venture HC, found it was only good for Geocaching so resold it only a few days later. Showed towns and main roads only.
This week I used an Etrex 20. good gadget for a budget. Showed position fairly accurate when matched to a paper map and showed paths. Could be better with OS maps downloaded perhaps. Would do a job but not the best.
The Garmin etrex 30 looks the best value with better options and mapping. Not tried it yet but does come up on this thread a few times. Cab get from £90 to £140 on Ebay. I think Ill end up with that unless I can save more. It does seam you get what you pay for with these things. Plenty out there better such as Oragon 600 etc but at a cost and watch for paying additional for maps. (I am old Skool with paper maps though)
