Too cold and wintery at Xmas.
 Need to carry all my gear for the week+ that I hope to be out.
 Too much walking too.
 I have a groin strain that won't heal - hense the bike option.
 Otherwise I'd be out there trekking hard.
 Keep the options coming as I came across a good site  
http://www.sustrans.org.uk/ and 
http://www.mbwales.com/ This last site I will look into as if all else fails, maybe I can do all the Welsh trails, plus whatever else crops up, not ideal, but may be an option. 
 Thanks thus far 
 Tim
