Yes, as long as the Lumo Run sensor is secured under your running belt or hydration pack in the center of your waistband or securely in the pocket of your Lumo Run garment, then these accessories should not interfere with your data collection.
Wearing Your Lumo Run Sensor & Gear
Can I wear the Lumo Run sensor with a hydration backpack or a belt?
Why do I need to tighten my waistband when wearing Lumo Run?
We recommend that you wear your shorts snugly, and not loosely, for the most accurate data. If there is excessive bouncing from the shorts, then it will impact the data capture.
