I will give a big shout out for those Vuelta Corsa Lite’s. They will do much better than anything Bontrager. However, tires can negate this if you choose a heavier and rolling resistant tire. Michelins rock in that department.
I will echo the need to track your rides and thumbs up for Strava, it’s fun, motivating and accurate enough to check your results on any given course including one of your own making (like the 11mi course you like).
