Hasta La Gadget!

If you’re running the 114th Boston Marathon on Monday or just cheering on a well-conditioned, pain-loving friend or relative, you’ll find some excellent tech there to help running performance. Sennheiser will have a booth set up to spread the word about the line of in-ear sports performance headphones it created with Adidas. The CX 680 (at left) won the Innovations Award at CES this year, due to its performance versatility. It’s insensitive to vibrations, can withstand cold and moisture, and cleans off easily under the tap.

Not all tech will be confined to the booth area: Jason, the CEO for RunKeeper, the best running app for the iPhone by far, will run the entire marathon dressed as an iPhone for the second year. This time he’ll be joined by Aaron, one of his company’s developers, who will be dressed like an Android phone to mark the app’s Android release. This is Aaron’s first marathon and he’s opting to run it in padding-free Vibram FiveFingers shoes (ca-razy!). Both guys are collecting donations for charity, so cheer them on with a little cash.
