Pollen Today
Pollen levels are today low across the route.
Air Quality Today
Air quality along the route is good, with all pollutants at low levels. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 20.8 km after start.

Environmental Exposure Detail
The Frankfurt Marathon is Germany's longest-established city marathon, first run in 1981. Its flat course through the city centre has only about 28 metres of elevation change, making it one of the fastest marathons among Germany's largest races. Frankfurt Marathon is one of European Marathon Classics' iconic races.
Held in late October, pollen is generally lower in autumn, though weeds and mould can still linger. Expect typical urban traffic pollution rather than pollen as the main air quality factor, especially through Frankfurt's dense city centre and financial district, while stretches near the River Main may offer a welcome break in air quality. With a route this flat and fast, many runners push hard from the start — all the more reason to know what you're breathing along the way. The local Airmine forecast along the course shows expected air quality exposure every 200 meters, helping you pace smart and protect your lungs over the distance. Push limits, not lungs!

Frequently Asked Questions
Where is air quality worst on the Frankfurt Marathon route?
Based on today's forecast, O3 is forecast at good levels along the route today (17.5/100). Air quality is at its worst after 20.8 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Frankfurt Marathon course?
Pollen levels are relatively low across the entire route today. This changes through the season as different pollen species become active.
When is pollen worst during the Frankfurt Marathon season?
Pollen seasons vary by location. Tree pollen (birch, alder) typically peaks in spring, while grass pollen rises in May-June.
How often is this forecast updated?
Updated four times daily. See the timestamp below for the most recent update.
Are pollen levels in Frankfurt Marathon based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Frankfurt Marathon, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
