I loved the RnR San Antonio race! San Antonio is a fabulous city, and the course was largely flat. There are some parts that have hills, and some not so shady parts. You get to run past the Alamo, which is super cool! I ran the 10k the day before and PR’d because the weather was so nice and the course was so flat. The aid stations were well stalked and the med tents were great. The volunteers really helped me through a rough patch at mile 18 of this marathon. Highly recommend San Antonio!
