Background - In the past, I've primarily focused on MTB XC racing. Won a regional championship this year (Cat 1), 2 state titles, and 5th (40-44) at Nationals in July.
I race with a local Cat 3 road team, mostly Masters age guys but primarily crit racing. This year, I did more crit racing than usual, and have ended up very close to the mandatory 40-point upgrade to Cat 2. 38 points at present. I didn't race a crit until June, almost all the points have come since then; won a training crit but best "real" results have been a 2nd in the Masters' 3/4 race at the US Crit Championships and 4th Cat 3 at the NC State Championships. Various other top 3-7 finishes, including a 7th in 35+ (first Cat 3 by several places) in a big regional race.
Crits aren't really my strong suit at 140 lbs and no sprint to speak of (most of my training has been FTP-based due to XC racing). I won 40+ in the Boone-Roubaix road race, 6th overall (unsanctioned, but a big race with TONS of steep climbing and gravel). 3rd in Love Valley Roubaix (after a flat early in the race) on a similar course.
I do well in the "A" training races (1/2/3) locally and often make the break, or contest the sprint. A few top-3-5 finishes there.
Next season I plan to focus more on the road side of things; my only real MTB goal is Marathon XC Nats in Georgia.
So.... given that I'm 40 already, most of my road racing will be crit-based (just not enough open road racing here), and I'd have to find a new team (unless I only race Masters)...
Should I apply to cat up? Either way, I'll be modding my training to accommodate the different racing focus.
Thanks for any relevant experience or advice.
