I received a link to another Google Maps site recently from one of my mates who I cycle with (thanks Greg). So anyway on this site you can track the course, locale, and distance of where you are exercising - how cool!
So, this is ideal for organising cycling trips; basically a map is plotted out - posted to the Internet, discussed, agreed upon, printed out and then basically executed (ah the hard bit - getting out and cycling in 14 degrees and rain - like I did last Sunday).
I have cycled this course three times and believe it is an ideal 2-3hour ride out of Zurich and v.scenic and (in parts) exhausting ;)
Zurich - Egg - Zurich: 35km cycle
One site to keep for training for 'Around the Bay' - 2007; yes Jacinta - I am committing to this!
