I've been lining 'em up and knockin' them down - running out of ideas and could use some fresh ones. Here's what I have left:
1)Trail marathon or ultra
2) Sun 17 min 5k
3) sub 2:50 marathon or just run a flat fast marathon course
4) Empire State Building race
5) 100 Mpw, once
6) cross country ski race or biathlon
7)duathlon
