The Bia is a two-part product. The single-button, touch screen wearable watch never requires charging and comes in a variety of colors. The rechargable Go Stick houses all the GPS - and thus, instant workout upload goodness. While folks initially had concerns about bulk, the Go Stick is no larger than a packet of Gu. It has also been updated to have a life of up to 17 hours - long enough for 100K competitors.

Ever open about their product development, Bia recently began including special plastic loops to help the current adjustable velcro band stay-put during rigorous activity. (Kickstarter backers and prior purchasers can request these free of charge.) EASE OF USE: No booklets, no slew of cords, no docks: the Bia's only instructions are a slip of paper that begins "Say HELLO to your Bia and don't freak out." There's no quick start guide needed. Within minutes, I was registered, had my husband set up via text message as my SOS contact, and was ready to head out the door on my first run. The Bia features a single button and a touchscreen. THE NITTY GRITTY: [Editor's note - functionality listing updated 8/29] It's not just a watch, a GPS watch, a stopwatch. Bia's instant updates have begun delivering triathlon functionality. Here's what a user can expect to find function for now, with * designating updates that are still in process. Any and all software updates happen quickly, updating the Bia to have new functionality without the user having to purchase the 'next' model. - RUN: just run, run/walk, intervals, indoor*, laps - BIKE: just ride, indoor* - SWIM: 25 yard*, 50 meter*, open water -MULTISPORT: brick, duathlon, triathlon, aquathlon, aquabike RUN TEST Christina tested this during: road runs, trail runs, track work (to test the 'slap to lap' function) "No more 'GPS dance' when I get ready to go running. I used to start my run-prep with turning on my GPS watch and putting it near a window, or right outside so it could find satellites. Plus, I usually run with my four legged run buddies, who aren't so good at calling for help if I fell and twisted an ankle. Knowing I can send an SOS alert with my exact location makes me feel safer when I don't have my phone. If I were a mom, I'd probably be the type to ask my kid to use the SOS function as a check-in if they were running solo. I'll totally admit I was wary of the Go Stick, but once I found a secure spot it basically disappeared. For my recent half marathon, I stashed it in my Hydraquiver, and have even clipped it to my dog's harness before."

As the person who tends to swim away from the rest of the group, the biggest thing for me was the SOS. Knowing I could basically call for help to my partner on land is some serious security. I clipped the Go Stick to my goggles outside my cap and was good to go!" WIN A BIA MULTISPORT GPS WATCH OF YOUR OWN Ready to score your own instant-upload GPS watch? It's simple!
