Rocky Ridge lives up to its name. The terrain is genuinely rough, with climbs that will have you questioning your choices and descents that demand your full attention. The payoff is real: views that are hard to reach any other way open up along the route. The shorter distances share the same character, hilly enough to be a genuine workout, with the same sweeping vistas.

The Rocky Ridge has been held every year since at least 2018. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the 3.1 Miles field finished slower than 48:55, and the last recorded finisher came in around 1:52:43, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (103 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 3.1 Miles, that spread matters more than the winner's time.
The 3.1 Miles winner ran 24:41 while the median finisher took 48:55. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
