BMA’s COVID-19 Recommendations for Safe Mountain Biking
The COVID-19 situation and subsequent Safer at Home order is not something to be taken lightly. Getting exercise and getting outside is extremely important for our wellbeing and mental health, but we must keep open spaces safe and uncrowded.
New sweet, sweet singletrack in West Mag!
A brand-spanking new one just opened on June 7 in West Magnolia! BMA is super excited to bring you… New 34 (official name TBD). It’s super flowy and fun and chock full of rocky bike-optimized alternative lines. And while we were up there last week, we also improved the trail intersection of Re-Root and Hobbit 1.
