it was a long back and forth but I have decided to discontinue also the service of tb-run.com.
Developing and running the site was a lot of fun and the feedback from the geocaching community was really great. But on the other hand, the usage of tb-run also went down during the last year.
I would like to thank everyone who contributed to this project. It was a lot of fun.
You can still access the current Races until Oct 12th. From Oct 12th day on, the site will be offline.
