Environmental Exposure Detail
Nøklevann Rundt 5K is an annual 5K race held in Oslo, Norway, usually held in October, drawing runners of all levels each year. The route follows trail and forest paths near Oslo, offering a change of pace from road racing.
Nøklevann Rundt 5K follows natural terrain near Oslo, where birch and native conifer forest are the main pollen sources along this route, with birch peaking through April and May, grass through June and July, and the season tailing off through autumn. Air quality is generally very good given the route's distance from major roads, though conditions can vary with wind and, in mountainous areas, temperature inversions.

Frequently Asked Questions
Where is air quality worst on the Nøklevann Rundt 5K route?
Based on today's forecast, O3 is forecast at fair levels along the route today (25.0/100). Air quality is at its worst 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 Nøklevann Rundt 5K 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 Nøklevann Rundt 5K 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 Nøklevann Rundt 5K 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 Nøklevann Rundt 5K, 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.

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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen 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. |
