Today i ran a 17 26 5k with 25mps cold and all year on the cc races i was 27 53 8k area hard courses .Why?

A 25 mps wind is extremely strong - 90 km/h or about 56 MPH. Not sure I understand your post, but the answer surely is YES!!!!

should i run a race mid week to try again .Or just keep as is till next weekend.

I think you will be fine. Some races are just different. 5k's might not be the best for you right now. Also to those people on here writing about this persons grammer needs to get a life. So what if things were not spelled correctly or capitilized! Answer the question & leave ugly comments to yourself. People on this board really upset me sometimes. Now back to your question, yes you can run 34 if you rest this week. Don't let this time affect your mind. Conditions play a big factor on race day. Add a little more speed to your workouts and cut back on the miles for a while. See if that can make a difference. Good luck in your future events.
