I'm 58, married w/2 adult children "still" living with me (cost of NYC real estate!). Live in the Bronx, NY near the largest ocean/forest municipal park in NYC.(Pelham Bay Park) Taught for 35 years, now retired, former NEH Fellow and still taking courses at NYU. Used to run for Millrose AA back in the 70's. Lucky to have known and worked out with Bill Rodgers, Frank Shorter, Tom Fleming during the heyday of the running boom when Jim Fixx wrote his "Complete Book of Running"
I've run around 15 marathons and 100 road races, not quite as fast as greenalfa but broke 6 min. pace twice - used to average 6:10-6:20 pace in races. Now I'm working hard to race in low 8's. Am a member of NYRR (New York Road Runners Club) so there a lot of races to run (nearly every week, most in Central Park). Left running in the 80's for bike racing and duathlons, then serious bodybuilding in my mid to late 40's - big mistake. Still trying to lose muscles developed during that time. Was 6'1" 240 like a rock and paying the price now at 205 w/arthritic knees but getting there.
My running schedule is not set, sometimes I mix in gym workouts but try to get in around 40 miles a week. A far cry from 5 a.m. 10 milers, work, 10K p.m. double workouts. Best challenges now are Speed X Distance, Quadrathlon, Team relay races. They force me to cocncentrate on more quality than quantity which I was doing at the inception of Nike+.
Immediate goals are going under 200 lbs., train at sub-9 pace, race at sub 8:30 pace.
Besides greenalfa, where are all the other 55+ yr. old runners from the 70"s???
