I've noticed that my times for mtb climbing have slowed. I'm now posting my 3rd best, 4th best, or slower on Strava on several segments. This baffles me as I feel pretty good going up these climbs. Now, I have been off the mtb a lot, mostly focused on my road bike. Times for climbing and TTs have steadily improved on the road bike though. Is it unfamiliarity with the mtb and/or my road climb hills are just not as much of an anaerobic grunt? Or, something else? Thanks.
