Help Me Decide Which Race

Okay, so I thought I would put this out to the forum. It is definitely racing season as there are too many races going on the same day.

My options are either an open water swim race or a bike criterium race. The races take place on Canada Day, Friday July 1st, so this is a stat holiday and I won't be working all weekend.

Here's a bit more details about each:
The open water swim race is $40. There is an option to do either the 1km, 2km or 4km race. I believe that I could do any of the distances, though the 4km would be more of a challenge. The people who do this race are generally swimmers not triathletes, so times are fast. MOP for the 4km race is under 1 hour. I'm a little better than a 2min/100m swimmer over a distance. The shorter the distance, the more "non"-swimmers that register. I've done the 2km race in 2003 and 2004. In 2003 I finished BOBOP (okay close to DFL), in 2004, I was BOMOP/MOP.

The criterium is a large race that goes through Yaletown in Vancouver. There will be a lot of spectators and really nice prizes. There will also be lots of good cat 4 female racers there, but I've been racing criteriums once a week since the beginning of May, so I should be able to keep up with the pack, though I probably won't win or win a prime, so it's not likely I'll win a prize. I would lean towards this race, but the downside is the cost. The race cost $35, but I don't have a license, so I'd have to buy a 1-day race license. The one day licenses are $10 or $30 depending on which one I need. I'm not sure which one I need so I should phone and find out at lunch time today. I will update the thread when I do find out the cost of the license.

The swim starts at 8:00am and the bike race starts at 1:30pm. I could probably do both races, but then I might be too tired for the bike race. I might not be though.

What do you all think?

Thanks,
Jen
