Marathon Fade

Post by ATimmins » Tue Nov 30, 2010 12:57 am

Do you think runners with time goals should plan for a slight fade due to fatigue? I know that "negative split" is desirable, but from my racing, and anyone elses, is fade always evident?  Is it a product of bad pacing or just lost of elasticity and fatigue?

There was a similar discussion last year around this time...http://www.therunzone.com//viewtopic.php?p=8368#p8368

I think you can look at a slight positive split retrospectively and still consider a race well executed, but it is courting disaster to plan ahead of time for a positive split.  Since you never know your exact fitness when the gun goes off and don't know how the conditions will develop during the morning, it is a fine line between a well executed "planned fade" of 1-2 minutes and a complete blow up of 10-12 minutes.  Better to embed a margin of safety into your race and plan for a faster second half.
