Why tough?? Well last week, I ran the most Kms in a week that I have ever done - 35 KLms - AND most of it was done early mornings under really COLD ( for me ) 3 degrees C conditions.
Why rough?? Wife and I were camping with a bunch of friends in the dry dusty grounds of the Tara camel races - and , as such things necessitate, there was a daily 4PM "happy hour" involving the use of much red wine to attempt to offset the pain of camping overnight in such freezing conditions.
This is what C25K has brought me to!!!
