I swim, bike and run. Then, I come here and write about my adventures. It’s as simple as that. Most of the time. If you’re new around these parts, here’s the long version of my story.

In Depth Product Reviews
You probably stumbled upon here looking for a review of a sports gadget. If you’re trying to decide which unit to buy – check out my in-depth reviews section. Some reviews are over 60 pages long when printed out, with hundreds of photos! I aim to leave no stone unturned.
Read My GPS Recommendations.
Here’s my most recent gadget recommendations guide (2012) – covering almost every category of sports gadgets out there. Looking for the equipment I use day to day? I also just put together my complete 2012 ‘Gear I Use’ equipment list, from swim to bike to run and everything in between (plus a few extra things). And to compliment that, here’s The Girl’s (my wife’s) list. Enjoy, and thanks for stopping by!

Read my Top 25 most useful posts.
It turns our I’ve written a fair bit of stuff over the past few years – and after it disappears from my front page, a lot of it never really sees the light of day again without Google’ing skillz.

Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
