Race?

So Bike month finishes with 28 straight days of riding to and from work, training, rides, etc.......all in all 625 miles logged for the month of May. To date, as of July 1 this year a total of 1244 miles since I started; with the bulk of it in April and May.
A friend suggested I started racing...........as an outlet, as a goal, as something to work towards to. I kind of scoffed at it, but signed up for Bike DC in May.....a fun 19 mile ride, and the Air Force classic....a timed ride/race - 62.4 miles within 3hrs.
I finished, but without its casualty; cramped legs and stiff IT band for 2 weeks.....
2 weeks before the "race", I mapped out a riding schedule, that included commute only days as well as long/endurance rides as well as quick and climbing intervals. A target mileage of at least 100 miles/week.
After the race, i could feel my body reacting to the "schedule"......I am not as conditioned as I was this time last year. Or perhaps the heat this year was more unbearable than last year? Migraines started and has prevented me from riding for almost 2 weeks. Is it because of my slightly elevated blood pressure? Allergies? I am ahead by 20% in mileage and speed compared to this time last year. My climbing skills is better than last year.....and I am actually enjoying it. But what gives?
I even have a far superior bike than last year; one that I personally built/assembled and currently only weigh less than 16lbs.
I've set my sights on next year's Triathlon, also some local Sprints and centuries as part of my training goals.
Crit? No thanks....need team and Peloton experience.........maybe next year?
