I recently got an email from someone that said:

“Dear Coach K,

I wanted to ask your advice.  I have been running fairly regularly for the last 7 years.  Last year I completed my 5th marathon and was very happy with my progress.  I am thinking that I am ready to take the next step and dive into a 50k distance race but am not sure I am ready.  What advice can you give me to help me decide if this is a good idea?”

I get emails like this fairly often so I thought I’d post some thoughts.
