Löplabbets Ribbemaraton runs through the Stockholm city streets and waterfront in this popular Swedish half marathon, with birch, oak, and linden as the main tree pollen sources along the urban route. The May race date coincides with the intense Swedish birch pollen peak, while the Baltic Sea coastal setting means onshore winds can periodically disperse pollen and the flat city course creates broadly consistent exposure throughout this Stockholm spring marathon event.

Frequently Asked Questions
Where is air quality worst on the Löplabbets Ribbemaraton route?
Based on today's forecast, O3 is forecast at good levels along the route today (18.7/100). Air quality is at its worst after 30.6 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Löplabbets Ribbemaraton course?
Pollen exposure peaks at km 31.3 today. This changes through the season as different pollen species become active.
When is pollen worst during the Löplabbets Ribbemaraton season?
December coincides with peak mugwort season. Grass pollen typically 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 Löplabbets Ribbemaraton 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 Löplabbets Ribbemaraton, 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.
