Garmin Forerunner 620 Watch GPS Accuracy Issues

In the comments section of my recent review of the Garmin 910XT a friend mentioned that he had seen reports of GPS accuracy issues for the Forerunner 620. Fellrnr also has done some extensive testing of various GPS devices and his 620 did not fare well. Garmin has acknowledged this problem, and has a sticky […]

Setting Running Goals: Shorter and Faster for 2014

For the past several years I’ve been in marathon mode. I don’t know exactly why or how it happened, but I fell into the trap of feeling like I needed to run a marathon (or three) every year. To be honest, ever since qualifying for Boston back in 2011 I haven’t really enjoyed the marathon […]

Nike Free 5.0+ Running Shoe Review

Update 3/14/2014: Nike has officially introduced the 2014 Nike Free shoes. Click here for images and details on the Nike Free 3.0 v6, Free 4.0 v4, and Free 5.0 v2. I have a fairly long history with the Nike Free line of shoes. My first step into more minimal footwear was with the Free 3.0 v1 back […]

Wireless Bluetooth Headphones for Running: Jaybird Freedom vs. Jabra SPORT+

I’ve been running a lot this winter with my iPhone 5s using the iSmoothRun App along with a Magellan Echo watch (the Echo controls the phone and displays my run stats). One of the nice things about running with my phone is that I have access to my music, podcasts, audiobooks, and Spotify – lot’s […]

Garmin Forerunner 910XT GPS Watch Review

My first ever GPS watch was the Garmin Forerunner 205. I loved that watch and used it on every run for several years. It was rock-solid when it came to tracking, the battery seemed to last forever, and it carried me through multiple marathons without issue. My only real issue with the 205 was that […]

Fitbit Accuracy For Counting Running Steps

I have a confession to make: I love my Fitbit. I’m actually a little bit addicted to it. The little guy does a good job letting me know when I’ve been a sedentary slob – a run-less day sitting at my computer will typically net me only a few thousand steps, which is my indicator […]

How Running Saved the Life of an Olympian: Lynn Jennings’ Story

I met Lynn Jennings for the first time last summer. She had emailed me out-of-the-blue earlier in the year to ask if I might be interested in coming to Craftsbury, VT in July to be a coach/speaker at one of the annual adult running camps. It’s not every day that you get an email from […]

B2R Trail Performance Shoe: Guest Review by Christian Messerschmidt

I am writing this review of the brand new B2R Trail Performance shoe as I recover from a 50K trail race last weekend. In that race I broke two paramount rules of long-distance running: 1. “Do not go out too fast”- I did, hung with the lead pack for a while, and crashed and burned […]

Maximalist Running Shoes: Some Thoughts on the New “Trend” in Running

The new trend in running shoes is maximalism: beefed up shoes with lots of cushion. Maximalism was triggered by the growing popularity of shoes made by the brand Hoka One One. Hoka started as a niche brand within the trail ultrarunning community, and has expanded its line to include road shoes as well. I’ve posted […]

Unbroken Movie Preview: The Story of Louis Zamperini

My wife has been on my case for months to read Unbroken: A World War II Story of Survival, Resilience, and Redemption. The book, by Laura Hillenbrand (author of Seabiscuit), tells the story of Louis Zamperini, a runner who competed in the 5000m at the 1936 Olympics in Berlin. The book tells the story of […]

Asics Super J33: How A Running Shoe Changes Barefoot Gait Mechanics

Runblogger Forum member Michael recently posted a video from Asics that features the Asics Super J33 running shoe. The Super J33 is kind of the stability version of the Gel Lyte33, a shoe that I like a lot. I bought the Super J33 as well for a review, but have not had a chance to […]

Rotating Running Shoes: Thoughts From Saucony

The concept of rotating shoes is one that I have written about many times, as have others in the running blogosphere. Yesterday I posted about how foot strike changes with running speed, and I touched on the fact that different shoes might thus be appropriate for different workouts. I’ve also written about a study that […]

Thou Shalt Not Laugh at a Fellow Runner

This week a video of a runner wiping out on a snowy street went viral – if you haven’t seen it yet have a look: I couldn’t help but laugh at the irony of the situation. I’ve been lucky so far this winter. Given the cold, we’ve had snow and ice on the sidewalks for […]

Effects of Running Speed on Foot Strike Patterns and Identification of Multiple Heel Strike Types

It’s becoming more and more clear based on existing research (and research coming soon) that foot strike patterns in running are influenced by a wide variety of factors. It’s not simply the case that humans use a single foot strike type under all conditions – factors like footwear, surface hardness, speed, and experience all seem […]
