This is my next request to make trainning plausible:

Perhaps duration is quite long, but some rest is including, and running in dense clouds, fog and mud above knees is quite difficult.
Can you make this trainning plausible?

It's Ultra Trail du Mount Blanc, because of difficulty of the race and high elevation gain it takes long time to finish.
