The Human Bean: Training for a 50k by eating nothing but beans for 40-days

Here's something different! An Aussie named Beau Miles ate nothing but beans for 40-days to train for a 50k Ultra Marathon and to see what the impact would be.

The video which is 26 minutes long is worth a watch.

"Eating only the contents of 191 tins of beans over 40 days transforms Beau into The Human Bean, and in doing so gives him a front row seat into how one food, totally and utterly, dictates how he feels. Beau uses his intimate knowledge of running to compare his former self to his bean-self, logging lacklustre training for an ultramarathon that he plans on running during the final day of the experiment."
