If its raining or the road is damp dont ride behind the person with raceblades on. You will get covered in crap from the road.
Keep an eye on the guy infront more, i found sometimes you cant look around much especially if there is someone that isnt as confident because i have found that they will grab their brakes when there is really no need.
A tip i was given by someone in the club was when decending look for someone who knows what lines to take and who are confident and get on their back wheel.
If your going to do some overtaking when going up a hill or going down a hill then make sure you look behind and check there is no-one there. I have seen someone nearly be taken out by someone just moving out and going.
Remember where the cafe stop(if there is one) for next time so you can shoot off and get their first.
