Okay. Here we go again. I just registered myself for the next Berlin Marathon in September. This time I want to be significantly faster than last year. To be specific, I want to make the 42,195 km in less than 90 Minutes. So I call this Projekt Jäger 90. Let‘s see how it works out.

Maybe I will repeat the Real Time Tracking Project I did last year. But I‘ll need much better gear to do that as last time the batteries lasted only half the time and my backup GPS system lost track in the third quarter of the route.
