Want to run your first marathon? There's a watch for that.
-The Nike Women's Marathon and Half Marathon is the largest women's race in the world, with thirty thousand runners taking to the hills of San Francisco.
But training for the race is a much lonelier road.
Samantha Hirsch and Krystle Lohmann ran hundreds of miles, often solo, with only their Nike FuelBands keeping them company.
-It really pushes you and like lets you know and you're not just like out on an aimless run, hoping you get certain amount of miles.
-The FuelBand track steps, calories and overall
A new version, the FuelBand SE, launches in early November and promises to recognize more activities; whether it's yoga or tennis, with greater accuracy.
For added motivation, runners pair their fuel bands with mobile with apps, like Nike Training Club.
-That's been wonderful and pushing me along, so I make sure that I post all of my runs to Facebook, so I can get cheers along the way.
-Those cheers are sent by friends via social networks and heard by runners via the app on their phone.
Running apps are helpful
for runners and trainers alike.
-I'm also able to, you know, tap into their Nike+ account and just see and maybe check out on them and make sure that they're actually doing the run.
-Fitness trackers like the FuelBand, cover the basics.
-The very beginner, the person who is still sitting on the couch should get a FuelBand, because that's gonna let them know, alright I have a goal, I need to burn x number of calories.
-More serious runners may want to consider a GPS watch, which connects to satellites to log your runs more
Tomtom offers two models, one for runners that tracks outdoor and treadmill runs and a multi-sport version that's desigened to track swimming and cycling as well.
Adidas will start telling it's miCoach Smart Run Watch on November 1st.
It features an optical wrist sensor that can measure your heart rate.
If you're on the Nike ecosystem, you'll likely wanna stick with its GPS watch.
-Definitely like the split times that the GPS watch has.
I love knowing my pace, I'm a huge
OCD when it comes to pace so I could stay right on pace.
And then distance of course.
-The technology is providing runners with more stats than they'd ever had.
And enabling beginners to tackle even marathon distances, but there is a downside.
-You can get overwhelmed with numbers and spend more time doing that than actually doing the exercise.
-Instead on being fixated on your wrist, try enjoying those miles.
