Last Friday I was invited to join altrarunning smartwool and REI for their Winter Warm-up 5k in Denver to celebrate the launch of their new line of winter running apparel 🏃🏼‍♀️ The Merino wool material not only was super comfy, but kept me dry and toasty warm on the 5k. You can check out the collection by visiting the link in my bio, available exclusively at rei #running #winterrunning #runner #gofarfeelgood
