The Sansa Clip Zip has been discontinued, and being arguably the best MP3 player on the market, prices are risking. I found some refurbished to stock up with, but it’s sad to see the replacement player is junk. http://fellrnr.com/wiki/Best_Running_MP3_Player

I've updated my advice on running in the heat, based on the available science and my experiences at Badwater and the Keys 100, as well as training in the North Carolina summer. I've tried to keep things simple, but the advice on clothing gets a bit nuanced as a lot depends on the level of heat and humidity you're facing. Let me know what you think. http://fellrnr.com/wiki/Running_in_the_Heat

I expected great things from the shoe designed for Meb Keflezighi's (winner of the 2014 Boston Marathon), but… http://fellrnr.com/wiki/Skechers_GOmeb_Speed

The New Balance RC1600 is a nice shoe and highly recommended, though there the placement of outsole material is a tad bizarre http://fellrnr.com/wiki/New_Balance_RC1600

+Raina R. what problems do you get from the flexibility?

I've added details of the GPS chipsets used in various watches, as I've had so many questions about which chipset is best. (I've also results for the iPhone 5S)

If you're looking to transition away from traditional shoes, then the #Saucony Cortana is worth considering as a halfway house. Compared with the Kinvara, the Cortana is closer to a traditional shoe, so try the Kinvara first. http://fellrnr.com/wiki/Saucony_Cortana

My article on the science of hydration has far more detail than you're likely to need unless you're a researcher, but it explains why I believe running in the heat requires far more salt than is in most sports drinks. I recommend adding 1/4-1/2 teaspoon per quart/liter. (I also added some surprising information on rehydrating with beer) http://fellrnr.com/wiki/The_Science_Of_Hydration

Excellent article. Thank you.

I've added a widget that will tell you the best price on shoes from various companies by gender/size/color. I think this is really cool functionality, and I'm excited to have it working. Let me know what you think! http://fellrnr.com/wiki/Shoes (Don’t worry, this won’t change my brutally honest reviews.)

CoolSculpting is cold to reduce body fat, which sounds like nonsense, but the approach is well supported by the research. CoolSculpting triggers natural cell death in fat cells over a period of months following the treatment. I've also found you can get a similar effect at home for free, which is better than the $1,500-$4,000 it costs at a doctor. I've updated my article on CoolSculpting with the latest research, including initial suggestions that massage after treatment enhances the results. http://fellrnr.com/wiki/CoolSculpting

I've updated my GPS accuracy analysis with the iPhone 5S. In my testing I found that different apps had radically different accuracy (RunMeter was the best I tried). I also added information on the GPS chips used in the different watches. http://fellrnr.com/wiki/GPS_Accuracy

+Panos Simandirakis I've not tested the F3 yet, though I'd like to. I get a sense of how watches are likely to perform from the emails I receive from users, and I suspect the F3 is going to have problems.

The Adidas Adios shows the potential of their new Boost foam, but the Adios fails to deliver. The heel is too high (11mm!), the toe box is grim, and it's far too heavy. http://fellrnr.com/wiki/Adidas_Adios_Boost

The LunarSpider is a good shoe, but Nike’s cheaper Streak is better. http://fellrnr.com/wiki/Nike_LunarSpider #nike
