Want to get exercise on your lunch break but don't want to go outside? Join the tunnel walk for a brisk 45-minute walk led by a volunteer through MIT's famous tunnel system. This walk will include stairs/inclines. Wear comfortable shoes. Free.

Tunnel Walk Leaders will have a white flag they will raise at the meeting spot for you to find them.

Disclaimer: Tunnel walks are led by volunteers. In the rare occasions when a volunteer isn't able to make it, we will do our best to notify participants. In the event we are unable to notify participants and a walk leader does not show up, we encourage you to walk as much as you feel comfortable doing so. Always checking the website just before you head out.
