Nik, you’re a very lucky guy!

I think for those out there who are already efficient runners, landing midfoot/forefoot, you're already half-way there to running barefoot.
The transitional period should be less and your calves will already be used to taking most of the impact.
For us heel strikers, finding out that we've been running so wrong, taking most of the impact through the heel, bones and knees takes a little longer to adapt. I've managed to build up to 1 hour runs now (mix of road and trail) but I think when I get a chance to go completely off-road soon, I will be able to run a lot longer. Some things I've noticed are that when I'm on road, my cadence increases, I’m guessing to adapt to the conditions (this appears to happen naturally). Also, when I first stated to run through mud and wet grass I was slipping all over the place but I think my gait must have again adapted to the conditions because I can now run quite comfortably. The same goes again with running over stony paths. At first they were a pain in the arse (well foot really) but slowly I'm finding that I can endure it and quite enjoy the feeling you get. My claves no longer ache! I’ve also noticed that instead of pounding along, I almost feel like I’m floating when running (anyone else get this feeling?). Oh…and I can’t help but run with a stupid big grin on my face!

The only negative aspect I’ve discovered so far is that I now hate wearing traditional shoes of any kind!
