Weaknesses: Just doesn't work as well as the old yellow model (of which I has 4 pairs) but I can't quite figure out what's changed apart from the colour. I think it might be more stable and that's restricting the movement of my foot too much.
Overall: Still a good shoe but where I did several ultra marathons in the previous version I just don't trust this one to go the distance. I also suspect it's contributed to some recent injuries.
'NEVER AGAIN SAY, “WHERE AM I?” 20 MILES INTO YOUR LONG RUN'
Strengths: Accurate, reasonably light and packed full of features. Can load data onto the computer and it gives course profiles.
Weaknesses: The signal is lost running through the woods. Not good at measuring short interval sessions. The lap button is not in a good place.
Overall: This has become an extension of my arm – it’s difficult to tell you how much I love this gadget. I used to plan runs, measure on maps using bits of string or awkward little wheely-devices. Now I just strap on the Garmin and go. I’ll explore all the various routes and always know how far and fast I’ve been. It even has a map to at least get me back to a previous part of the route if in doubt (useful for running during business trips to Holland). It seems very accurate and consistent and the only down side is running through the woods where the signal is lost. It's also good for programming interval sessions. Brill!
Strengths: Lots of science stuff - worth reading if you can stick with it. The biographies of the great runners are fantastic, including good training advice. Especially ggod for marathon and ultra runners.
Weaknesses: Big & heavy! Complex.
Overall: The Bible. I constantly dip into this and found the ultra advice really useful for the London to Brighton this year. The author seems to know his stuff. I especially liked the advice on injuries, "never accept a final opinion from someone who isn't a runner"
