Big point in all this is that I’d like to break through and deepen my aerobic base in hopes of improved mtb or gravel race performance for events over 2 hours:
Regarding the group ride. TR Planned a typical over under type at 1.5 hrs and 110 ish TSS. 4 person group ride was a fair bit of threshold when pulling and SS and easy in draft, so surgy efforts with the pulls. Ride was 2:15 hrs and 170 TSS. That added about 60 TSS on the week and the other weeknight rides all went higher than planned a little for the previous two weeks too this resulting in about +100 TSS over amount in the TR plan each of those weeks. (like 520s vs 420s planned). The TR MV-SS and build blocks only put me at 6-8 hours per week and only occasional TSS weeks over 500). I feel like a could handle more as long as the intensity on the more part wasn’t high.
I’ve done MV SSB 1 and 2, short power build, and specialty last season. Started the same this season in Jan, but ended after the build with cancelled Wilmington race which was the A for June 6. TR put me back into SSB1 and this is switching to build as of a week ago. Legs were feeling toasty after what I described and I took this week as a rest week and planned to re-set the Planbuilder plan this monday so rest weeks are re-set otherwise I would’ve been fried after 5 weeks on the gas.
It seems/feels like subbing a longer 3-4 hr Z2 ride on sunday for the TR workout which is usually SS for a two hour workout. Might add aerobic base without too much stress. Also seems like it’d trigger the aerobic system better than just adding 15 or 30 min to a could a few times per week. This is my biggest wonder actually.
Thanks for your advice @bloya89 !
