yea that's a pretty huge CTL, and also it looks like OP had negative TSB for a good 3-4 months straight. without any winter base to sustain it, I'm surprised he's not ready for a 3 month nap right now..

Alex - just don't sit on your ass all winter. when you do, you're not starting from zero (i mean, starting from ~3.5 w/kg ain't nothing!), but you're severely hampering your potential. i also imagine those first couple of months kinda suck, when you do start riding again - i know they do for me, right now, coming off of about 3 months of no training due to injury.

you care enough to post here and ask, so just do it. you've had a huge build and load this year already - unless you have some target events coming up, just spend the rest of the season riding for fun, and enjoy yourself - don't worry about keeping CTL up. when you feel yourself petering out, give yourself a 1-3 week rest, no bike at all. but then GET BACK ON IT.

oh and most importantly, congrats on the weight loss and loving the bike now stick with it!!
