Today's blog by Sean Blair

It's January again, and for many, including me, it's the time to pick running back up again, and shed a bit of the festive excess.

Enter Janathon.

Free to enter, it's a month where you can run every day (or do any form of exercise) and blog everyday. For me, mostly it's a great way to start a year with a great online group of like minded people.

I've got my first 70.3 Ironman in May, so I'm wanting to be fit for that, as well as the Brighton marathon in April.

Since Berlin marathon last October my running has suffered, an exceptionally busy work period and home life are the top two excuses...

So I'm going to go back to basics and build by aerobic base. Essentially see if I can get fitter by measuring my time at any given mile or kilometre at the same heart rate.

If this works out, by the end of Janathon I'll be going faster at the same heart rate.

Tonights run, a 10k to Westminster and back set the benchmark, and I'll do the same run at the end of Jan to see if I've improved - or not.

An alcohol free January, something I often do, should help me be lighter - and feel better!.

Happy Janathon everyone, and may 2012 be your fittest and best year yet.
