I think they are fair points, I’d always advise anyone that TR for Tri is making bike the focus.
But critical is which plan(s) you are talking about - TR is not a philosophy, and the plans vary significantly. As above I did Olympic Build MV which is three hard bikes a week, leaving no room for hard work in the other disciplines, but HV does have room. And LV is different again. Plus if you are talking about the bike-only plans, those obviously have no room designed for the other disciplines.
My running is 321 or “BarryP”, or at least it is meant to be! I tried run focus on intensity last year so I’m trying run volume this year. And whilst it has allowed me to train swim and bike more easily - I’m clearly having a problem getting the runs in.
It’s too early to tell but after my posts above I got in my Thursday and Friday runs in, both with new routes and timetables to start making a new routine:
M Brick short run
T Evening club run, medium
W Lunchtime short run before lunch
T Run between dropping and picking up my daughter’s evening class, medium
F Short run at woods on school run route, and avoid traffic
S/S Long run early before family wakes up
