welcome. you hit the key with, “…have fun with a few…”. always be ready to adjust and adapt. you might end up with some dual race weekends, or maybe bag one after a tough week before. its all about the flow.
we too are lucky here in Michigan with more multiple race weekends than ever before. i’d like to see some early evening, mid-week, summer sprints.
oops…wasn’t supposed to say anything 
It’s been a busy year! One 1/2 marathon, 2 off-road duathlons, 3 sprint tris, 2 half IMs, one full IM (CdA) AND 3 open water swim races (1500m, 5K, 12 mi relay).
Every year seems to be different. My first year of road racing (running) a buddy of mine and I raced every weekend for like 3 months straight, 5ks, 10ks culminating with a half marathon…probably ended up doing something along the lines of 20 races that year, but none of them were multisport events.
This past year for me was:
–2 5k road races
–1 10-mile sort of off road race (Tilden Tough Ten)
–1 sprint tri
–1 Oly tri, 1 Oly DNF (3 flats on the bike)
–2 HIMs
–1 Ironman
9 races, 1 DNF
With IMW06 as A race, here’s my race plan/goal for the year prior:
10/05 - 5M (2x) (speed work)
11/05 - 10M (B)
12/05 - Trail Marathon (B); 12K (C); 10M (C)
1/06 - 20K (C); 13.1M (C)
2/06 - 15K (C); Trail 50K (C); RR-40+ cat (B)
4/06 - Trail 50K (A); RR-40+ cat (B)
5/06 - RR-40+ cat (B); 20M (C); AmericanTTTsolo (C)
6/06 - RR-40+ cat (B); HHH 200K bike (C)
7/06 - Muncie HalfIM (C)
9/06 - IMW (A)
.
god, a lot, it just depends how much $$$ you have, your schedule and how fast you can recover. This season I did:
3 running road races, 3-8 miles
1 trail run race 10m
2 bike road races
3 bike Time Trials
1 Mountain bike race
a couple biathlons
7 Xterra races
4 sprint tris
4 olympics
1 half IM
I think I race to much but it’s so fun I just can’t help myself!
I think I did 26 or so Du’s, 4 cycling road races & 6 running races.
