Course & elevation
Shamrock is flat and fast, built for first-timers and personal bests. It heads north through residential streets and along tree-lined Shore Drive past First Landing State Park, then turns south through the resort area. The only notable rise is the bridge over Rudee Inlet before the course returns north for a boardwalk finish.

The certified route
A coastal course from the Cavalier Resort area, north on Atlantic Ave to an out-and-back on Shore Drive, back south through the oceanfront and along the boardwalk, then south on General Booth Blvd to turnarounds at Prosperity Rd and S Birdneck Rd, returning north to finish on the boardwalk at 30th St.
- Start
- On Pacific Ave at the north edge of the crosswalk before the entrance to the Cavalier Resort, 4 ft 9 in to the front edge of the storm drain north of the crosswalk.
- Finish
- On the boardwalk north of 30th St, east of the Hilton Hotel at 3001 Atlantic Ave, 13 ft southeast of the southeast corner of the second storm drain north of 30th St, marked with a masonry nail and washer in the bike path.

Key moments
- Mile 1–10North through neighborhoods and along Shore Drive by First Landing State Park, flat and steady.
- Mile 16Rudee Inlet bridge, the lone short rise on an otherwise flat course.
- Mile 24–26.2Back north for the famous Boardwalk finish near the King Neptune statue.
Pacing strategy
A flat course that rewards even or slightly negative pacing. Keep the early miles controlled despite feeling fresh, ease over the Rudee Inlet bridge by effort, and use the flat boardwalk return to finish strong.
Pacing by goal time
Checkpoint splits for four common goals at Shamrock Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.
| Checkpoint | Sub-3:00 | Sub-3:30 | Sub-4:00 | Sub-4:30 |
|---|---|---|---|---|
| Mile 3.1 | 20:366:51/mi | 24:027:59/mi | 27:289:08/mi | 30:5410:16/mi |

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.
Plan your mile splits
Turn your goal time into a mile-by-mile plan for Shamrock Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.
Plan Shamrock Marathon splitsFueling & hydration
Water stations appear roughly every 1.5 miles with Gatorade Endurance, and on-course energy gels are offered around miles 5.5 and 19. Carry your own gels too and fuel on a fixed schedule; an onshore wind can mask sweat loss.
Weather
Mid-March Virginia Beach is usually cool for racing (40s–50s), with wind off the Atlantic the main variable, sometimes a headwind on the oceanfront stretches.
What race morning has actually been like
The last 5 editions of Shamrock Marathon, measured at the start line rather than averaged across the month. Starts have run 39–62°F, averaging 51°F.

Is Shamrock Marathon a good Boston qualifier?
Yes. Start and finish sit at the same elevation, so no downhill adjustment applies and a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
Compare every course, how the downhill bands work, or work out your own target.
