Stage 2 Calf strain, oh boy!

I can ride, but I can't run. Just tried a little "jog" and there is NO WAY I can jump barriers this weekend. That means I'll be missing out on the State Championship CX races this weekend. $#@^&***%@$# *#&^#%@*^%$#@!!!!!!! Hopefully if I don't try to do too much I can make Vande-Cross in November...$%%%^$@&*(&$+###@@$ &
