Michael's race report:

Sounds like he thought he had it won.

re: bacu

Thanks for the postings to both blogs.

It is interesting to read the recaps from both runners.

Arnstein's diet is nothing new. Raw fruit and vegetable diets have been around for a very long time. I have read the 1, 2, and 3 star reviews of the book on Amazon, and have to agree that the emphasis on fruit is too much, at least from my personal experience. It is way too high in sugar, and low in the mineral content that comes from veggies.

The diet that I have found best, for me, is the one from "Diet & Salad" by Norman Walker. The emphasis is on raw vegetables, including raw vegetable juices, with fruit as a supplement. The problem with juicing fruit is that, rather than feeding the cells at 2 or 3 calories a minute, it causes sugar spikes of 200 calories a minute.

It is strange that the guy who wrote the book says that raw vegetable juices cause sugar spikes, which they don't, yet he advocates fruit juices, which do! Anyway thanks to Michael Arnstein for his fine race and the inspiration for me to focus more on my diet again.

Geb could run 5:30 as a training run.

A good, but not real fast US runner, Oz Pearlman just ran 5:25 this fall in Chicago. Many 2:35 - 2:40 guys have run 5:30. The WR for 50 miles is 4:50 by Bruce Fordyce, a 30:30 10 km guy. Even if Geb is one of those guys who simply struggles to easily transfer marathon speed to 50 miles, fully trained and on an average day he could still get the WR and run in the 4:40's. If he has a bit of muscle resilency (and one would think he does) a 50 miler in the 4:30's is quite doable.

re: hard to say

re: Jurek

50 miles really isn't his thing, he's more attuned (or was) for the 100mi distance and WS fit him perfectly as well

Michael also has a YouTube channel where he talks about his racing & diet: http://www.youtube.com/user/marnstein#p/u/1/lXCeM82rqMM
