Strava details here.
Today's ride was a late-afternoon jaunt (roughly 24 miles altogether) around East Arlington, mainly the hillier sections along Fort Caroline Road. It was quite windy (a pre-frontal trough passed through that dumped a lot of rain last night & this morning, with a thunderstorm around noontime). The portions of the ride that were the hilliest (upper-right sections in the map above) had residential streets that had some really short yet punchy climbs averaging about 5-6% gradient - one hill in particular was quite steep with an 11-13% gradient near the top - that one was marked in Strava as a segment: the "(Un)Pleasant Hill Dr Climb" (tee-hee!).
There's no need to tell you that this is one of my favorite riding areas in Jacksonville!
