Guichet on preparation

I think in a second lengthening would be well 4cm, but in the first i think you should do 6cm.

Try to become flexible enough to touch the ground with your palms while keeping your legs straight. I've heard that is good preparation. Have you spoken to Dr. G yet? If so, how did he come across?

I think Dr. Guichet is a bit over the top with this.  Most people who have done LL will agree that going into it with good fitness and flexibility is really helpful, but being an Olympic athlete is uneccessary.  Yoga is great prep there are a lot of good stretches for things that don't get enough attention IMO, like pigeon pose for the IT band. 

Might as well enjoy running for as long as you can, cause it'll be a long time before you can do that again and maybe never at the same level :/

Does anyone has an idea on how to prepare with stretching? -> http://exercise.about.com/od/flexibilityworkouts/tp/12-Great-Stretches-for-the-Lower-Body-Maximize-Your-Flexibility.htm -> I would do 3-4 leg exercises from this website and rotate them during the week. Moreover, I am working in the gym, doing the leg press about 100 lbs (I'm 1,62; about 143 lbs), and leg extension (femur) with 50 lbs.

Would that preparation would be sufficient enough?

ShyShy has mentioned in his diary, that he gained 40 % strenght during preparation, and that he went from 90 degrees "stretchability" to 125 degrees.
Would that mean for instance that at the end of preparation I should be able to to 140 lbs on the leg press?
