Zone 2 Training (or lack of!)
I'm in my second (1st serious) year of triathlon, and I've gone down a line of thinking that I hear is quite common:
"The faster and harder I train, the faster I'll be come race season".
Here's an example of my training programme, which has changed little since October. My main targets are sprint and olympic distance triathlons, towards the end of May through to mid June.
T: am - Core and Flex pm - Hour intense swim
W: pm - Club Ride
T: pm - Running intervals (250m - 1500m)
F: am - Spinning intervals pm - Hour swim
S: Club Ride
I don't run more than once a week to avoid shin splints and my technique isn't good enough to allow me to do long steady swims. Therefore, my only "Long Steady" work is on the bike on Wednesday and Sunday. However, I always get tempted into going with the fast group, meaning I hang on the back for 2-3 hours and am absolutely shattered when I get back.
I have been reading a lot recently (and now understand the science behind it) that Zone 2 work is absolutely critical to endurance athletes, and I have done almost none of it through the season.
Zone 2 is certainly something I'll make an effort to incorporate into my training over next winter, but is it too late now? If you think I will benefit from Zone 2 training now, how many sessions a week should i do and for how long to benefit come my target races? Would I be better keeping up the intervals as always?
I really appreciate any advice. Let me know if what I've said isn't clear.
