Came to the conclusion now after doing several group rides that they will either be races or almost no stimulus at all. I will need to go back to the old school of SST training but this time I can do a group ride or race with people at my level so I am not discouraged as I was in my younger days and my doors were blown off.
Time to dust off the old Training with Power book and get those 2 and 3 x 20 out.
