Went out biking with a couple other guys who work at Rackspace on Sunday. We rode the Mission Trail in San Antonio from near Concepción to Espada. Total of 19 miles and I'm not nearly as sore as I thought I'd be this morning.
For those not familiar with the Mission Trail, it is mostly a wide paved sidewalk with modest hills and a gentle slope. The scenery is interesting and there are few cars to fight. We saw a number of birds, including a Snowy Egret, Comerant, Cardinals, Red Tailed Hawk, and a Vulture circling over us.
