Where did my legs go!

I have not raced since xmas after dislocating my shoulder, untill tonight and honestly my training has been pretty spasmodic with all the wedding planning.  Tonight i decide to race again.. But i soon realised that over the last 2 weeks my fitness has dropped off quite a bit. For the first 20 minutes i felt ok, but then when the speed increased i just didn’t have the legs to go with it. I realised what was happenin s  just continued around to the finish.  After getting dropped off the group i made a few solo efforts to ty and getback, but i just didnt have the power. OH well, lesson learned.. keep training!!
