where it's at wrote
Bay Area is the answer. Shorts and t-shirt weather every day of the year. hundreds of miles of trails, elevation in Tahoe/Yosemite/mammoth all within 2.5-5 hours where you can go from sea level to 7500'+ before lunch
great running clubs, tons of hills in the city, Golden Gate park (20% larger than central park) marin headlands, mt tamalpais, on and on
I love San Fran, but you must live some kind of fantasy life going from golden gate to Mount Tam in the blink of an eye. Mammoth in two blinks???
