I HEART Lactic Acid Structure Mug

C₃H₆O₃. The molecule responsible for the burn. Your oldest enemy and closest friend.

Most people avoid lactic acid. You train specifically to increase your lactate threshold so you can sustain higher intensities before it kicks in — and then you push past it anyway. This is not normal behavior. This mug is for people who know that and do it anyway.

Whether you're recovering from a track workout, arguing about aerobic vs. anaerobic energy systems, or just need something to hold at 5am before a long run, this enamel mug gets you.

• 12 oz lightweight enamel mug
• Durable — survives aid stations, drop bags, and the dishwasher
• Great for hot or cold beverages
• Perfect gift for the runner who loves the burn (and can explain why it happens)
