They are owned by active.com and have a Terms of Service that prohibits scraping/crawling the website.
After searching active.com's website I don't see any information about an API for coolrunning.com or how to get a developer key.
This single site has the results for >90% of races. People voluntarily upload results, and then forfeit the right to pull down and store that data?!
Somebody working for active.com please reply with instructions on getting a developers key to the API ... I don't care about stealing your business, I want it to be a side project to at least improve the Results section..
