100

Correction, today marks my 100 day countdown to the marathon.  Marathon day is actually 102 days away, but I'm not running the Saturday before the marathon and marathon day is not really a training day (if I'm not ready by the 14th, I'm not going to be ready), so I'm counting Saturday, January 14 as the beginning of Marathon Day...  the longest day of the year (37 hours for those scoring at home).
