Pollen Today
Pollen levels today are none across the route.
Air Quality Today
Air quality along the route is fair. O3 (27.5/100) is fair. The remaining pollutants stay at good levels. Based on Airmine's forecast, which uses satellite data to calculate exposure every 200 metres along the route, air quality is at its worst 2.6 km after start.

Environmental Exposure Detail
A 10 km race route climbing toward the summit of Gaustatoppen from Rjukan, crossing alpine terrain above the treeline with sweeping views over Telemark.
Gaustatoppen 10k climbs the dramatic Gaustatoppen mountain in Telemark from Rjukan, where birch, alpine grasses, and crowberry are the main pollen sources in this dramatic mountain setting. The enclosed Vestfjorddalen valley below concentrates pollen under calm conditions, while birch peaks through May on the lower slopes, alpine grasses contribute through June and July at higher elevations, and the elevated setting compresses the season significantly throughout.

Frequently Asked Questions
Where is air quality worst on the Gaustatoppen Loop route?
Based on today's forecast, O3 is forecast at fair levels along the route today (27.5/100). Air quality is at its worst after 2.6 km into the route. Airmine calculates exposure at 200m intervals along the course using satellite-derived atmospheric data.
Where is pollen highest on the Gaustatoppen Loop 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 Gaustatoppen Loop 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 Gaustatoppen Loop 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 Gaustatoppen Loop, 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. |
