This has happened to me twice now, most recently at IM Copenhargen a couple weeks ago.
Upto 140km on the bike I'm averaging 37km/hr. Into the second loop and I'm loosing the plot and my average at T2 for the 180km was 34km/hr.
I have changed my build training this year and stopped with the long 5-6 hour outdoor sessions.
I moved to an inner-city location so my "long bike" session comprises a very early Sunday start on my road bike before the traffic and 3/4 hours of circuits with some tasty hills/drags then home a straight on the trainer/TT bike for 90mins Interval work.
Mid-week I do either a 60/90/120 duration trainer/interval session depending on where I am building to the event.
So my power output has increased this season but I'm fading on race day.
It's not nutrition or bonking as a did a 3.45 marathon....
Is my new training plan wrong...??? Any advice welcome...ch
