If you have "good wheels" (other cyclists of a similar level or a little higher than yours) by your side, setting a pace and giving relief, it should not be a problem to reach the finish line and set a good time. The problem is if you hook from the beginning to a group stronger than you, in a few kilometers you will be exhausted.
In my case, the trick is to shoot, shoot, shoot ... and the day of the race, enjoy especially if you go with friends.
Although you still have time, I wish you luck.
At the end of September we have the flight to Gran Canaria and this year will be especially hard.
