monty has it pretty well explained. he and i were both pretty much sub-16 (but not by too much), off of tri training. at least i think we were sub-16; i don’t believe the mechanical clock had been invented yet.
here’s one very memorable training bloc i was in when running at my best, and i guess i’m a little embarrassed to write it, but, after a too-short warm-up, i’d run 16 minutes out on an out-and-back, turn around, note my turnaround spot, and then run back. i counted it as a new record if i got further out than i’d gotten before, as long as i got back in less time than it took me to go out. i always had to negative split. that was my rule.
if i did that today, i’d be toast in 3 weeks. but when i was a young 'un i could get away with stuff. you can give yourself a lot of rope with 25mi/wk. 1 x 10mi run, medium-stiff pace, and 3 x 5mi runs, pretty stiff pace, you can get very fast on that, esp if you’re also swimming/biking.
i was quite close to liz downing, who i’m sure you never heard of, but if you were a triathlete in the last 80s or early 90s she was a household name. this is when duathlon was called biathlon and it was a big part of multisport. liz didn’t lose a race in 5 years. liz rode one USA Cycling race in her entire life, and in that race she broke the women’s 40k national record by a minute and a half. she was a terrific talent. i was her bike sponsor throughout her career. she told me during 1 of her unbeaten years that she calculated all the miles for the year that she ran, divided them by the weeks in the year, and it came out to 11 miles a week. so, you don’t need big miles to run very fast if you’re a multisport athlete.
Thanks for the insight! Sadly I hadn’t heard of Liz but I will definitely do some research now.
