"Alan Geraldi must leave his suburban San Francisco home by 6 a.m. if he wants to get to work by 10 a.m. His office is only 23 miles away, but his commute is by foot. Morning commutes in the San Francisco Bay Area can often take an hour or more thanks to freeway congestion, but ultra-marathoner Alan Geraldi leaves his gas guzzler behind and runs to work.
The 44-year-old attorney, who races in 100-mile 'ultra-marathons,' says soaring gasoline prices prompted him to take up these twice-a-week runs earlier this year. A favorite stretch takes him across an overpass spanning an often congested freeway. On a recent commute, he points to a sea of headlights.
'See, it's already getting backed up,' Mr. Geraldi says between short breaths. 'I like that.'"
