Well, I’m 10% of the way to 100 vertical miles. I should be considerably further at this point but our four-week vacation (Jan 17 – Feb 13) decimated my average daily ascent. Going into vacation, my daily average was 1,294 feet per day. At the end of vacation, it was down to just 730 feet per day. Ouch. 🙁 While 100 vertical miles is an uphill battle (pun intended) at this point, it’s not impossible. As the weather improves, riding longer each day (and therefore with more climbing) should get easier, at least in terms of comfort.
