The 2004 Triguide from Inside Triathlon Mag has an article by Mark Allen called Pitfall Prevention 101. Mark’s suggestion for bike/run bricks is to go extra miles on the bike and limit the run portion to less than 50 minutes. (e.g. 125 mile bike ride, then 40 or 50 minute brick run.) He actually said to toss out those 15 mile brick runs and that doing a brick run longer than 50 minutes will actually diminish your fitness.
Is this an effective brick workout? Most of my peers comment as they exit the Ironman events wishing they had done longer brick runs. One of my peers, after IM Florida, said he is going to start doing two hour brick runs, following a long bike ride, to prepare for his next IM. Will ‘going long on the bike’ and ‘limiting the brick run to 6 or 7 miles’ properly prepare you for the Ironman?
The article is pretty good and right to the point in avoiding the pitfalls of training. In magazines and on the internet, there is an abundance of training advice out there, but when a six time world champion gives advice, you’re more inclined to listen and heed the advice. The suggestion of limiting brick runs to only 50 minutes seems to fly in the face of what most IM athletes perceive they should be doing on their brick workout days. Your thoughts?
