Polar M400 Review

Here's my review of the disappointing Polar M400, which has poor GPS accuracy and no cadence support. It would have been a great watch if it had been released back in 2010, but not now.

Updated suggestions for Gifts for Runners

It's a little late in the season, but I've updated my list of gift suggestions for runners. I've added some more books, including the Oatmeal and The Old Man and the Sea (best book on ultrarunning ever).

Saucony Hattori Review

I've added a review of the Saucony Hattori, a remarkably light, minimalist shoe. It's been discontinued, but it's still available. I compare it with the Mizuno Wave Universe, Asics Gel Hyper Speed and the Altra One2. I'm also working on the comparison table to add in the 12 shoes I'm testing at the moment.

GPS Accuracy Update for Garmin Fenix 2

Sadly the firmware upgrade that improved the GPS Accuracy of the Garmin 620 so dramatically didn't work as well on the Fenix 2. The accuracy is better, but it's still one of the least accurate watches I've tested and the "lost satellite" bug remains. (I'm currently testing the Polar M400 and its GPS accuracy is disappointing. In fact, the M400 is disappointing overall; Polar has a ways to go before it catches up to Garmin. I've just received my 920XT, but it's too early to have any sense of its performance.)

The Science of Running Shoes

I've systematically reviewed the available research on running shoes. The results may be a little surprising, but hopefully you'll find them useful. (I found over 50 relevant research papers that I've cited, but if you know of any research I've missed, let me know.)
