The short answer
The best MeteoPace alternatives cover its paid splits for free. Racecast gives free forecasts and a weather-adjusted pace calculator, Wyndo a free heat calculator and race history, TrueEffort free hill-adjusted splits from your file, and GPX Forecast free weather along a GPX. RunFast's Map your run times heat stress to every kilometre, free.
Key takeaways
- MeteoPace's free tier previews race weather; personalised splits need a $8.99 Race Pass or Pro.
- Keep paying if you want plans sent to a Garmin or COROS watch.
- Racecast and Wyndo are free for named races; TrueEffort and Map your run read your own route.
- No free tool here does everything MeteoPace Pro does, so pick by the gap.

What is MeteoPace good at, and who should keep paying?
MeteoPace is one of the most complete race planners for runners, and if you race often with a Garmin or COROS watch, it may be worth paying for. Before you pick one of the MeteoPace alternatives below, know what it does. It leads the race planners in our comparison of the best running weather apps.
As of October 2026, MeteoPace:
- plans "any supported race" from the forecast, historical norms and the course profile;
- turns them into a Meteo Adjusted Pace and a split-by-split plan, in min:sec per km or per mile;
- covers marathons, half marathons, 10 km races and ultras, with more added on request;
- models your heat adaptation, writes weather to Strava and sends plans to Garmin or COROS watches;
- runs on iPhone and Android, with free race pages on the web.
Its home page quotes a Runner's World Gear of the Year 2026 mention; we haven't checked that with Runner's World.

Strengths
- Weather, hills and 10 years of history in one adjusted pace
- Sends race plans to Garmin or COROS
- Heat adaptation modelling and Strava write-back
Limits

- Dew point not shown on its pages

What does MeteoPace give you for free?
A preview. Without paying, you can add your first race, see its race weather and read a general impact range for your finish time.
The plan itself is paid, as of October 2026:
- Race Pass: one race plan, no subscription, with forecast updates and a send to your watch. $8.99 on the US App Store.
- Core: training weather and Strava write-back, from $5.99 a month.
- Pro: unlimited race plans, adjusted splits and heat adaptation, $9.99 a month, after a 14-day trial for new customers.
That's fair value for a target race. But if you want splits for several races or your own route without paying, the free tools below cover most of it.
How did we choose the MeteoPace alternatives?
Each had to give, free, at least one thing MeteoPace keeps behind its paywall: weather-adjusted pace, splits, or weather along a course. We compared them from their own sites and US App Store listings in October 2026; we did not test them. Map your run is ours.
Which free alternatives come closest?
Five, each covering a different part of the plan.
Racecast
Free forecasts for thousands of named races, a RunScore from 0 to 10, and a free calculator that adjusts pace, finish time and splits for the weather. Where a course is mapped, the calculator adds its hills and the wind along the route. Its full Race Plan costs $9 once. See Racecast alternatives.
Best forFree forecasts and a weather-adjusted pace calculator for named races
Strengths

Wyndo
A free heat-adjusted goal pace that shows its research: Ely (2007), El Helou (2012), Mantzios (2022) and Vihma (2010). It gives a range, not one number. It takes one set of conditions, so it can't follow a race that warms up. More in Wyndo alternatives.

Why do splits matter when the race warms up?
Because slower runners spend longer in the warming day, and meet the heat earlier on the course. One adjusted pace for the whole race hides that; splits show it.
At the 2018 Berlin Marathon, by RunFast's ERA5 race-history data (reanalysis, not a thermometer at the start line), the start was 14 °C (57 °F) for everyone:
| Finish time | Pace per km (per mile) | Warmest air, °C (°F) | Hottest feels like, °C (°F) | Moderate heat stress from |
|---|---|---|---|---|
| 3:00 | 4:16 (6:52) | 19.7 (67) | 19.7 (67) | km 26 (mile 16.2) |
| 4:00 | 5:41 (9:09) | 20.4 (69) | 22.4 (72) | km 21 (mile 13) |
| 5:00 | 7:07 (11:27) | 21.1 (70) | 23.5 (74) | km 16 (mile 9.9) |
The 5-hour runner meets Moderate heat stress 10 km (6.2 miles) sooner than the 3-hour runner. Ely and colleagues (2007) found slower marathoners lose more time as WBGT rises. Official race flags and medical advice override any plan.
Which MeteoPace alternative should you pick?
Pick by the gap you want to fill:
- A plan on your watch: stay with MeteoPace's Race Pass or Pro, or check what Garmin's race day weather shows free.
- Free weather-adjusted pace for a named race: Racecast.
- A free, cited heat adjustment: Wyndo.
- Hill-adjusted splits from your own file: TrueEffort, free on iPhone.
- Weather along any GPX: GPX Forecast.
- Heat stress and splits for every kilometre of your route, free: Map your run.

Questions runners ask
How much does MeteoPace cost?
As of October 2026, MeteoPace is free to download. Its US App Store listing shows a Race Pass at $8.99, Pro at $9.99 a month and Core from $5.99 a month, with several yearly options from $24.99 to $59.99. New customers get a 14-day Pro trial. Prices vary by country and exclude local taxes.
What can you do in MeteoPace without paying?
Add your first race, see its race weather and read a general impact range for your finish time, as of October 2026. MeteoPace calls this a preview. Personalised splits need a Race Pass or Pro, and training weather needs Core or Pro. The free web race pages also show course climbing and the race window's history.
Is the MeteoPace Race Pass a subscription?
No. MeteoPace describes the Race Pass as one race plan with no subscription: a weather-aware pacing strategy, race-day forecast updates and the option to send that plan to a Garmin or COROS watch. It cost $8.99 on the US App Store in October 2026. If you race often, its Pro plan covers unlimited races.
Can MeteoPace plan a race from my own GPX file?
Its pages describe planning "any supported race", with a form to request races that aren't listed yet, as of October 2026. We found no option to plan from your own route file. For that, TrueEffort reads GPX, FIT, TCX or KML files on iPhone, and Map your run reads GPX, FIT or TCX files in any browser.
What is the cheapest way to get weather-adjusted race splits?
Free, if you mix tools. Racecast's pace calculator adjusts pace, finish time and splits for the weather, and Map your run gives a hill-adjusted split for every kilometre with the heat stress you'll meet there. Among paid options as of October 2026, TrueEffort Pro at $8.99 a year adds weather to its splits, and MeteoPace's Race Pass costs $8.99 per race.
