Get well soon Mathschick - I agree with juggler, I'm a fairly cautious trainer and figure I'm never as close to being injured as when I'm upping the miles and running at new limits. These days I try and keep my baseline fairly high (30's) and then I'm never upping miles to a massive extent week-on-week. It took awhile to get to that baseline, I've done gradually more each year, but if I work from that I seem to be reducing injury occurance or severity every year.
Speaking of progressing training, that made me have a look at my mileasge logs and I'm close to my biggest year yet.
2004 = 748, 976, 1118, 1411, 1369, 1792, 1863, 1975,....
2012 = 1943 and not out, I'm coming for you 2000
