frisbee 1:30:00 
Slightly unfocused session (not my fault, but the organisers). Was going well during the all too brief drills section, before they dived headlong into a game and I managed to aggrevate my quad within literally seconds, so sensibly (read unbelievably!) retired from the session and spent a few minutes warming down properly and stretching (like I should at the end of every session).
Quad is obviously going to be a problem if I don't rest it (much like my rib), however with term ending imminantly I think I will soldier on for the last sessions and to try and get at least some skills benefit, and not injure myself further at OUOC circuits!!
