I ran a 15k yesterday

When you're training for a run, there's a rule that you're only supposed to add about 10% of your distance a week.

Since recovering from cancer, I've been adding about 10% per run. 

I thought because my body had been used to running, it would be ok. 

It did work well. I'd be tired and a little sore after a run, but overall feel pretty good. 

I ran a 10k last week. It went pretty well. It was right about where i would have run six miles. It was a really good run. 

Next, we had a week of rain. I didn't get the chance to run after my 10k. 

Well, going from 10k to 15k is really tough. I think I was the last guy to finish. 

I did it, but my next run is going to be a much shorter distance. 

I think it's good to challenge yourself though. Failure should teach you a lot. I think I learned a lot yesterday.
