I love starting my runs here -- by following the trail, you can get in a 3-, 4-, 5-, 7- and/or 10-mile run. Plus, there is plenty of parking on the north or south side of the bridge!
Good place to park :) Running across the bridge is a nice way to end a run too.
Warning Thieves: Bait Car Might Be Parked In This Lot!!
Runing first, then walking...
Stop by the Austin Pets Alive table here every Sat/Sun from 9a-12p and borrow a dog for your run/walk. All animals are availble for adoption!
