I'll bet she does...

To me 50's is like being a teen ager, still look like kids, running certainly helps. I ran 5 miles per day, 7 days a week until my mid 60's. Never ran a marathon. !0 K's my limit then. Started training for a marathon once but, too much gun building got in the way, takes lots of concentration. Mental a big part of prep.

My idea of cardio is HIT body building Mike Mentzer style for a series of months and then alternating off of that back to some heavy power lifting. I HATE running! The endurance it takes to run a marathon is indeed impressive but overcoming the boredom of just running is what really impresses me.

the Amazing Missus and I are once again riding 'sweep' for the local marathon making sure no one is left on the rural, sometime near wilderness, course, nor that anyone with issues is abandoned. I carry basic first aid supplies including space blankets, extra water and energy bars and have done this enough times that I know I can reach the finish line with my ham radio (cell service is spotty at best). Marathoners are truly "unique", tho I am thinking another word!
