BTW I am not in the best shape of my life either right not, quite far from it in fact.

Last week end I took part in a 100 km bike race/marathon (it was the 2nd time I did it after last year's one), for which I prepared for about 8 weeks.
As I am not really fond of buying all kind of gadgets I only got myself one of those watches that measure the pulse, and as always I never used it until the race itself.
At the end of the race everyone was talking about various values like speed, distance and ofcourse pulse. And at this point I got a bit lost as I had a pulse of around 180 for 90% of the race while other people I was there with were all reporting peaks of 170.
So it looks that I need to get myself in better shape again.
