Riding with new cyclists

As someone who is generally slow all around, I HATE feeling like I am holding my "skilled" friends back.  I will actually tend to push too hard when training with a better athlete, and I have even hurt myself.   I DO see the value from training with these people.  I get to see better techniques and equipment.  I dont, however want to be a burden on the ones who help me in this way. 

I suggest that during your rides you do take a little time for yourself.  Maybe do some sprint intervals or something.  If you let them see you making the most of your workout it wil teach them to do the same.  But be up front about your plans.  Let them know that you want to help them but also need to benefit from the time.  I think they will understand. 

One workout that some of the more advanced guys do when we ride is that they'll do a 'fixed gear' workout.  Pick a gear, stay in it the entire time.  Pros do this workout occasionally (on purpose) too.  Builds power on the uphills, recover on the downhills.

Two caveats:  You should be a very fit cyclist to try this workout - it places quite a bit of stress on your legs.  There's THAT warning.  Also - it's a better workout if you have rolling hills...not as effective if it's flat, and not reasonable to attempt if it's too hilly.
