The model and avid runner shows how the hotly anticipated Apple Watch can be used to train for—and run—a marathon


As a follow-up to the Apple Watch announcement last September, the tech company shared some new details about the much-anticipated smart watch at yesterday's Spring Forward event. First up, an official release date: April 24th! Apple also announced the rollout an 18-karat gold and sapphire crystal edition, which starts at $10,000-because of course that's what you budgeted for an activity tracker, right? (There is a way to Track Your Fitness Without Shelling Out Any Cash.)

Equally as exciting (for us, anyway!) was Apple's reveal of their partnership with model Christy Turlington Burns, the first person to use the device for fitness tracking outside of Apple's headquarters.

Apple released a video that shows the three-time marathon finisher using the watch during the Kilimanjaro Half Marathon, which she ran to raise awareness and funds for her nonprofit organization Every Mother Counts, which works to make pregnancy and childbirth safe for every mother. Can this lady be more inspirational?!

Turlington Burns made an appearance during the presentation (straight off the plane from Tanzania) to talk about how she used the watch during the half marathon to measure her time and distance, and push her pace. "I relied on it quite heavily," she told Apple CEO Tim Cook. "The race was pretty challenging. There was a lot of altitude and elevation, so I was checking it quite frequently."

Her first blog post is up on now, and Turlington Burns will continue to document her training experience for the next eight weeks as she gears up for the London Marathon in April (she's hoping to beat her record and come in just under 4 hours).

Now, we're just counting down until we can get our hands on one of these bad boys ourselves!
