I'm a bit of an over exerciser. I recently injured my labrum doing elevated bench flys with two 40lb.s barbells. Stupid and unnecessary at age 66. But I've been an addicted walker for decades. I recently met a 70 year old retired physician. We were introduced by a mutual friend who knew we'd go well together as , "crazy old walkers".

Now I'm a decent walker, but old Doc has me panting. I walk with him from his home on the NJ side of the George Washington Bridge ( some good size hills in that portion), across to Manhattan, descend ~ 350' to the Hudson River coast path. South from 181st to 145th Street, to the top, ~50' ( 5 sets of stairs) to Riverbank Park, once around the Park and back to point of beginning, just about 11 miles.

Our best time is 3 hours flat. But we average between 3:15-3:30hr.s. The ascent/ descent from bridge to river is ~1/8 mi., STEEP, Doc is about 6'2". I'm 5'7" ( early in the morning, before my back compresses). His stride is so long that I have to shorten mine and take about 3 strides to match 2 of his. On a hot day, it's a b****! Nap time and a quart or two of water thereafter . But, all in all, not bad for two " crazy old walkers".
