The great debate continues over on RunningAhead - Is it beneficial or detrimental to run 20 miles or more or over 4 hours in a marathon training long run? Some vehemently insist that if you don't run atleast 20 miles a couple of times while training, then you are undertraining. Others, such as my coach, insist that if you run more than 18 miles or longer than 3.5 hours, it takes your body too long to recover and can, therefore, be detrimental to your training. Meaning, you would have to back off the long runs too far in advance of your intended race in order for your body to sufficiently recover. (Am I making sense?) He insists that this will not change unless I pop up to the 50-mile distances. (And yes, the thought does enter my drain bamaged mind, even though I only have one successful 50k completion - and I pooped and peed and puked all over myself in the process. . . . . Hell yeah I had fun!!!)
I suppose there will never be a definitive answer accepted by everyone, but I find people's opinions on the subject quite interesting, with each person standing firmly on his or her side of the fence not budging one iota.
And on the subject of long distances - Bizz Johnson is less than 2 weeks away. Egads! It's a Boston qualifier, so I looked up the time requirements for qualifying - oh yeah! That was a real knee slapper! And no, qualifying is definitely not in the cards. However, I am hopeful that I will finish in 5 - 5 1/2 hrs. We'll see!
