Perhaps a pre-season 4 or 6 week block of training focussing on VO2Max as a limiter?https://support.trainerroad.com/hc/en-us/articles/360001766351-Re-build-Off-season-or-Maintenance-for-Your-Fastest-Season
VO2Max efforts are always hard, and over several recent podcasts, Coach Chad has emphasized building up to this, starting with 30s/30s efforts (eg. Gendarme, Taylor), and gradually working up through 1 minute (eg. Baird), 2 minute, 2.5 minute and 3 minute intervals. Probably 2 VO2Max interval sessions per week is plenty.
