due to difference in mph and effort between mountain and road i record training, sorry riding in hours and over the past five years this has been as follows:-
2005 438.75 hours
2006 457.75
2007 418.75
2008 403.75
2009 425.50.
still a bit dodgy as 90 mins in a race is alot more exhausting that a five hour ride with mates that involves stoping to chat, map read and so on. i do try to exclude time spent not peddling but not a science. above is a mix of mtb, road and mtb on road commuting. overall ave of say 14 mph would give 6,000 miles or 115 a week that feels about right. for every trans wales or marmotte (i did both in 2009) there is a week drinking, tired, too much work, awful weather etc).
