I need more ‘miles in my legs’ before doing TR SSB2, for me SSB2 is a build not a base.
Couple seasons I tried TR Traditional and it helped, but TB1 didn’t have any intensity. So I did them outside and tossed in some intensity. Better.
To my eyes the TR polarized had a little too much vo2max, I’d dial that down.
Last I looked the bike portion of TR full distance triathlon looked more interesting, more aligned with what I know works for me.
