Course Narrative

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.

Around race day for Frankfurt Marathon in October, pollen levels are generally low, with occasional mould spore spikes in damp conditions. Cool conditions (around 12°C) tend to keep pollen release moderate, though occasional rain can offer brief relief by settling pollen in the air. As a mainly urban route, air pollution here is often worse on cold mornings, when traffic fumes get trapped near the ground, and on warm, still days, when ozone can build up — both affecting air quality more than pollen.

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 (16.4/100). 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.

Airmine uses satellite data to calculate pollen and air quality every 200 metres along each race route, updated four times daily. 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.

Methodology & Technology

Airmine combines satellite observations, weather forecasts and machine learning to forecast pollen, air quality and mold risk. For pollen, vegetation maps and weather data help predict season onset and exposure at 400 × 400 metre resolution. For air quality, we refine Copernicus CAMS forecasts using local factors such as roads, emissions and terrain. For routes, data is updated dynamically to provide accurate exposure metrics along the specific race corridor coordinates.

Our models are calibrated against millions of professional monitoring records and updated four times daily as new data becomes available.
