Highly Anticipated Lieberman Research Released

Dr. Daniel Lieberman from Harvard University has released his second Nature paper concerning human evolution and the way humans run. The latest paper, entitled "Foot strike patterns and collision forces in habitually barefoot versus shod runners", concludes that forefoot or midfoot strike gaits, which are more common when running barefoot or with minimal footwear, may protect runners from impact-related injuries now common to runners.

Dr. Lieberman has launched a Running Barefoot website as well that explains more of his research. There is also a video, released by Nature, that features an interview with Dr. Lieberman and some of his research.

I've been waiting for this research for a long time and can't wait to spend many happy hours reviewing it.

The Living Barefoot Podcast Show - Episode 9 Released

The latest episode of The Living Barefoot Show went online last night. It is the edited version of our LIVE event that we held in October. It was great fun, if a little stressful at times. Al and I will probably be doing more live events coming up later in the year.

You can check it out at:

Beautifully Muscular Calves

My last run was 4 minutes running, 30 seconds walking times 5 intervals. So still a total of 20 minutes running time. I really thought that this wouldn't be a problem after my last 3 runs before that had all been 2 minutes running, 30 seconds walking. It seems that I may have overestimated the running potential in my calves. I know this because it has been SO hard to walk down stairs properly for the last 2 days because my calves are protesting so much. :)

My last run was completely barefoot at the track as well. Even though I have pansy feet, it is still more fun than wearing shoes (any kind of shoes). Did I just write that? It's just that there is SO much more biofeedback from your actual soles hitting the actual ground with no shoe buffer; even 2 mm of flexible shoe buffer.

The 'pansy feet' comment was inserted because I noticed there was 'something' (I have no idea what it was as I was on an indoor track) stuck to the bottom of my left big toe for a few steps. I have no idea how long it was actually there but after it became bothersome, I stopped and removed it, and kept running. When I got home, I noticed there was a wonderfully developed blister on the bottom of my left big toe and I KNOW it was from said 'something'. I guess I need to further develop a pachydermatous (I love that word) layer of skin on my soles.

Anyway, back to the 'beautifully muscular calves'; if nothing else, this is what barefoot running is going to give me. So I'll keep working on increasing my running time and decreasing my walking time and all the while developing killer calf muscles while I'm at it!

Sore Calves - Finally

Yesterday, my barefoot run at the track was 10 intervals of 2 minutes running, 30 seconds walking; essentially doubling my running per interval but the same 20 minutes of running time overall. Today, my calves are unfamiliarly tight. It's been a long time since I've felt this sort of muscle discomfort because it's been such a long time since I've been able to work out hard enough for my muscles to protest this much. It's AWESOME! There is such a difference between self-induced pain/discomfort compared to injury pain; and the former is much more tolerable than the latter.

I think my next run will be the same workout and I'll hold off increasing intervals and running time. I think I'll give my calves a few days to heal, too before I run again. I guess my running buddy will have to settle for walking outside (now that the weather has finally warmed up a bit) rather than running.
