The high-tech treadmills at the new run-training studio Runaway aren’t the only things to get excited about (although, made by Woodway and featuring super-fast response to speed changes they’re actually pretty special). This sleek spot takes a personal training approach to group fitness, featuring coaches that guide you through interval cardio, strength conditioning, and soft tissue recovery. Ever-changing playlists are the icing on the cake. Optima Signature, 228 E. Illinois; runawayfitness.com
