I haven't ran a full marathon in 30 years the 6 weeks recovery for running one where I was shot and lacked energy was just not that pleasant. I ran 8 and received appearance money for it in the 1970's, my favorite was Grandma's in Duluth Minnesota. The Ethiopians and Kenyans were just getting an idea of what was possible for them at the time. I still run a 10 miler or half marathon but I continue to get slower and slower, I never even win my age class anymore, mainly at 55 now I just do it to stay in hunting shape. Congrats to you it is a good feeling of accomplishment but not for me anymore.
