⏵ Course guide · The original Rock 'n' Roll Marathon
San Diego is where the Rock 'n' Roll series began in 1998, a rolling loop through Balboa Park and roughly 14 San Diego neighborhoods with bands at nearly every mile. I will walk you through the terrain first, then give you a pacing plan built for the mesas and canyons, plus free tools to dial in your own numbers.
These facts come from runrocknroll.com/events/san-diego, including the confirmed June 5-6, 2027 race weekend. The exact race day and clock start time were not separately published, so confirm the current schedule on runrocknroll.com before you race.
San Diego's natural terrain, mesas cut by canyons, gives this course real elevation change from Balboa Park through downtown.
This is the original Rock 'n' Roll Marathon, founded in 1998, and the race that the entire national series grew out of. Starting at Balboa Park, the course winds through roughly 14 San Diego neighborhoods and the Gaslamp Quarter before finishing downtown, carrying the rolling character of the city the whole way.
True to the series signature, live music lines nearly every mile of the course, more densely than most Rock 'n' Roll events. Use it to hold a steady effort through the rolling terrain rather than letting the energy pull you into an unsustainable pace on the climbs.
This is not a flat, fast course. Elevation change repeats throughout instead of concentrating in one climb.
A flat-course pace target does not survive contact with San Diego's mesas and canyons. Run by effort using a grade-adjusted pace target, and expect your overall time to run a bit slower than a flat course at the same fitness level.
The cool, overcast June morning can burn off into warmer, sunnier conditions as the race goes on, especially away from the coast. If your pacing plan assumes the cool start temperature holds the whole way, you may be underprepared for a warmer back half.

No. San Diego is the original Rock 'n' Roll Marathon, founded in 1998, and its course runs rolling through San Diego's natural mesas and canyons across roughly 14 neighborhoods, starting at Balboa Park and finishing downtown. It is not a flat, fast course, but it is one of the most scenic and band-heavy in the series.
Early June in San Diego typically brings the "May Gray/June Gloom" marine layer, a cool, overcast morning that can burn off into a warmer afternoon, especially further from the coast. It is generally mild running weather, but do not assume it stays cool the whole way; check the forecast and be ready for the marine layer to lift as the race goes on.
The confirmed race weekend is June 5-6, 2027. The marathon and half have historically run Sunday morning around 6:15 a.m., though the exact 2027 day and clock time were not separately published at the time of writing, so confirm the current-year schedule on runrocknroll.com/events/san-diego closer to race day.
Pace by effort across the mesas and canyons rather than by a flat number. Because the elevation change repeats throughout the course instead of concentrating in one climb, a grade-adjusted pace target keeps your effort honest on both the ups and the downs, which matters more here than chasing a single flat-course pace goal.
It is the birthplace of the series. Founded in 1998, this is the original Rock 'n' Roll Marathon that the entire national series grew from, and it still carries the signature: bands at nearly every mile, a big field around 30,000 places across distances, and a scenic route through Balboa Park and the Gaslamp Quarter. The rolling terrain is the tradeoff for that scenery, so treat this as an experience-and-effort race rather than a flat PR course.
