im a sophomore on XC and track... i have huge problem. everyones getting faster, and i havent changed since last year. my race PR (5k) is 19:20, and i know for me this is horrible. this was in the beggining of the summer. its now late fall and im in the high 19s and low 20s. ive been running my butt off during practice, in fact we had a 30 400 work out and i ran almost all of them lower than 75 seconds.. thats faster than our #1.. now the thing is that i wasent running with the fast group. i was running in the slow group, which they start at different times and run seperatly.. but i was leading the pack, so i dont know if im better at a front runner or what. but on the last one, they merged the two groups, and i slowed way down. my legs were killing me, i felt sick.. well later that night i found out that i strained my para spinus (back) muscle and ive been out for about 3 weeks. my times are making me so mad, and im very dissapointed in myself. i realy want to know whats going on, if anyone could help, i would like to get in the 16's by my senior year, but nobody thinks i will, im on the verge of quitting
