Environmental Exposure Detail
Ivar Formos Minneløp brings runners to Sognsvann and the forested trails of Nordmarka for a memorial trail race in the woods north of Oslo. Covering distances of 3, 10, or 17 kilometers, it's a serious test of pace and endurance.
Mould spores and damp forest-floor allergens can be more noticeable in Nordmarka in October, particularly along shaded, wooded stretches of trail. Along the largely forested course, tree cover means fewer traffic-related pollutants than a city race, though damp autumn air can still affect breathing for sensitive runners.

Frequently Asked Questions
Where is air quality worst on the Ivar Formos Minneløp 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 11.1 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Ivar Formos Minneløp 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 Ivar Formos Minneløp 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 Ivar Formos Minneløp 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 Ivar Formos Minneløp, 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. |
