Unofficial Zilker Tri

Andrea and some friends are planning to do an unofficial sprint triathlon down at Zilker Park. Here is the route I came up with for the race. The course is as follows:

-Out and back in Barton Springs (about 1/4 mile).
-Under MoPac to do 3 loops through neighborhood (some hills, but it was the flattest course I could find without riding on busy streets) (about 9 miles). 
-A clockwise loop on the dirt trail around Town Lake under MoPac and back across at Lamar (about 3.5 miles).
-Finish is near the pool.

Here is a Google Maps version of the course with details like stop signs.
