I don't know how much value people will get out of this particular chart, but I'm a numbers geek, and having a visual just helps.
I have been recording my weight every day consistently for years. I can't find the sheets from mid-2003 to 2008 - they exists, just not sure where! In any case, you can assume I bounced around in the 190 range.
2008 - first full marathon. Weight came down nicely.
2009 - first Ironman. Weight was not low despite mega training
2010/11/12 - focused on PBs... consumed by them... managed my weight with ferocity!
2013 - mostly goofed around
2014 - Ironman #2... again, weight was not that low. And after it was done... YIKES!
2015 - Trying to reverse the trend, numerous set-backs, but I'm getting back on track!!!
As you can see I have always struggled, but that 185lbs number (the 25 BMI point) has usually been a good wake-up call for me. At the end of last year I really let that get away from me, so now it's going to be a big job to get back. I'm up to it, though.
