Mountain biking with a mask is better than no exercise at all

It was only after getting above Budhanilkantha that I took my mask off, as I gasped up the trail on Shivapuri. This is my morning routine: ride outside of the Ring Road until I reach an area with better air. Two hours later, I return down to the Valley floor, where I put the mask back on and ride the last 7 km into the city centre.
With Kathmandu’s air quality constantly at ‘Extremely Unhealthy’ levels there isn’t really another option.
Riding with a mask until reaching safer air and getting exercise is better than not exercising because of pollution.
Some studies even show cyclists are potentially exposed to less pollution than people in vehicles, so wearing a mask that reduces pollution by 90% or more is worth the risk (see health tips, below).
Despite the pollution, the Valley rim is still a great place to stay in shape. The ridges surrounding the Valley offer trails ideal for running and cycling, extending from forested hills through the paddy terraces far above the pollution. One can easily ride 2 hours in the morning and get above the dirty air, and still make it back for work. Or there are 4-6-hour cycling trips on weekends. The rides with Himalayan views, clean air, good singletrack and tasty lunch at village tea shops make for an excellent Saturday out on a bike.

Shivapuri Scar Route
Easily accessed by riding or driving to Kakani, enter the Shivapuri National Park (Rs1,565 for foreigners, Rs100 for Nepalis). Continue on trail until a fork taking right and left contours around the park. Left is more travelled by, with a technical singletrack and beautiful views for 10 km until Gurje Bhanjyang. Drop back to Kathmandu via Tokha and Grande Hospital or continue on. The loop can have as much as 30km off-road singletrack. Multi-day adventures include Chisapani and/or Nagarkot (single 12-hour+ day for extreme riders).
