Race day: 2026: 26 May,9 Jun,25 Aug,8 Sep
Distance: 5 km

Pollen levels are high today, with cypress and grass as the main active species. PM2.5 levels along the route are low today at 1/100, well within safe limits for outdoor exercise. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 0.0 km after start. Pollen exposure peaks at 1.9 km after start.

Markakarusellen 5km runs through the Drammen marka forest in this popular recurring trail series, where birch, pine, and spruce dominate across classic Norwegian boreal woodland terrain. The Drammen valley below concentrates pollen under calm conditions, while birch peaks intensely through April and May, grass from forest clearings contributes through June and July, and mugwort extends into September throughout this mid-distance Drammen marka trail series event.

Frequently Asked Questions

Where is air quality worst on the Markakarusellen 5km route?

Based on today's forecast, Go3 levels are at their highest after 0.0 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.

Where is pollen highest on the Markakarusellen 5km course?

Pollen exposure peaks at km 1.9 today. This changes through the season as different pollen species become active.

When is pollen worst during the Markakarusellen 5km 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 Markakarusellen 5km 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 Markakarusellen 5km, 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.

Levels show the highest exposure along the full route. Airmine uses satellite data to calculate pollen and air quality every 200 metres along each race route, updated four times daily.
