Christopher and I have now participated in the Houston Chevron/Aramco HALF Marathon 10 times together. The latest was, unfortunately, just a walk (no running due to plantar fasciitis) - but a very fast walk (3:06:15 - 14:13 min/mile)!! For Houston Chevron/Aramco, I have actually done 10 half marathons & 1 full marathon. Christopher has done 11 half marathons (he hit #10 last year) & 1 full.
