Environmental Exposure Detail
Drammen Half Marathon is an annual race held in Drammen, Norway, usually in September, drawing runners of all levels each year. Runners take in the sights of Drammen along the course from Marienlyst Stadium to Gulskogen and Stormoen, all on the Strømsø side, covering the same roughly 10K stretch twice — out and back — to complete the flat and fast half marathon course.
The course runs through the streets of Drammen, where oak and plane trees typical of the city centre are the main pollen source along the route, with birch peaking through April and May and grass pollen building through June and July. By the time race day comes around in September, pollen levels have generally eased, though weeds and mould can still linger in the greener stretches near Gulskogen. Air quality along the course is generally good on weekend mornings, though nitrogen dioxide and fine particulate levels can rise on the busier, more built-up stretches through Drammen's centre. The local Airmine forecast along the route updates continuously and can be followed in the days leading up to race day, so you always know what to expect before you start. Push limits, not lungs!

Frequently Asked Questions
Where is air quality worst on the Drammen Half Marathon route?
Based on today's forecast, O3 is forecast at good levels along the route today (14.1/100). Air quality is at its worst after 7.3 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Drammen Half 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 Drammen Half 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 Drammen Half 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 Drammen Half 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. |
