Sorry for hijacking a trail thread with talk of bikes on tarmac, but it's kind of related...
From late September 2017, up to and including Xmas Day morning, I was quite happy keeping my fitness ticking over by doing ~10000+ feet of hill reps each week around Copsewood/Dell/Woodmill. Usually extending my commute home to do 1000 feet, plus a few longer training sessions in MAMIL gear, with a vast majority of the sessions on the Wazoo.
In early December, I grabbed some better winter clothing kit, thinking I would continue doing this type of routine until spring.
But then I treated myself to a risky purchase of an Elite Direto just before Xmas, given its expense, my limited disposable income and my last basic turbo maybe getting 10 hours tops over its time with me until TimP on here bought it with my Tricross Singlecross.
And then on 28th December, I randomly decided to visit the South Downs cat4s, for the first time in almost a month... Loved it until I reached the plateau of Old Winchester Hill and then came so close to my first serious crash since Xmas 2013 on black ice!
Turbo training has its own negatives, like not getting outside to help alleviate SAD symptoms a little, plus learning to battle the sweat-fest and put as much effort into riding as I do outside... But that "near miss" on the 28th has overwhelmed me with negative thoughts of what if my front wheel goes from under me while I'm freewheeling down Woodmill at ~30mph, in the damp or on frost/ice.
I've even begrudgingly joined Zwift despite the £13pcm urine-taking price, but it's keeping me going, ~300 miles and ~23000 feet over the last two weeks (while Dan Evans has done an insane amount of miles and climbing this week in Gran Canaria on the STW Strava leaderboad!).
Roll on 10-20C temperatures and hopefully a bit of dry weather!
