Heatwave Half Marathon 2026: Multi-City Summer Series Explained
What is the Heatwave Half Marathon? How the 2026 summer series works across US cities, virtual options, and how to find your local event and results.
· 5 min read · Athletics News
The **Heatwave Half Marathon** is a summer road-race series that runs across multiple US cities from July through August, with both in-person and virtual options. Each city hosts its own event on a separate date, but the branding, distance, and registration flow are shared through a common race platform.
If you searched "Heatwave Half Marathon" looking for a single national result list, the structure can be confusing. There is no one combined leaderboard - results live on each city's registration page.
How the 2026 series is organised
Each city event is a standalone half marathon (21.1 km) with local start times, courses, and result sets. Cities in the 2026 calendar include Houston, Austin, Chicago, Kansas City, Fort Worth, San Antonio, Columbus, St. Louis, Des Moines, Fayetteville, and Ann Arbor, among others.
Dates vary by market. Austin is scheduled for 19 July 2026; Fort Worth for 25 July 2026. Check the registration page for your city for exact start times and course maps.
Virtual participants can submit times through the same registration system after completing the distance on their own route.
Finding Heatwave Half Marathon results
Results are published on each city's RunSignup results tab, not on a single national page. To look up a finish:
1. Go to the registration site for your city event. 2. Open the Results section. 3. Search by name or bib number.
Some locations post live results at the finish area on race day. Preliminary results may be updated after chip verification.
Is Heatwave Half a Boston qualifier?
Course certification and Boston-qualifying status vary by city and year. If a BQ matters to you, confirm the specific course certification on the event page before registering. For current standards, see [Boston Marathon qualifying times 2026](/blog/boston-qualifying-times).
Compare your target finish against [average half marathon time](/blog/average-half-marathon-time) and [good half marathon time](/blog/good-half-marathon-time) benchmarks, then use the [half marathon pace chart](/blog/half-marathon-pace-chart) for race-week pacing.
Training for a summer half in heat
July and August start times often mean warm conditions. Practical adjustments:
- Start conservatively - heat raises heart rate at the same pace. - Hydrate before the gun, not only at aid stations. - Adjust goal pace by 10 to 20 seconds per km if the forecast is above 25°C.
A [half marathon training plan](/plans/half-marathon) with a final long run in similar conditions helps more than cramming speed work in the last fortnight.
