Design-a-crit - Airfield

So, I'm working with the Marine Corps Air Station where I am to layout a crit for later this year. I'm no criterium expert, but one of the things I've already been approved to do is use our airfield for a race. My current plan will be to plan/propose two events. The first will be a 5km time trial the length of the runway and parallel taxiway.. ala:
http://www.gmap-pedometer.com/?r=855169

Simple enough, right? Well, with essentially unlimited space, turn options I'm curious to know the racers' takes on a criterium course. I threw this one together briefly, but feel free to propose your own. The course layout is pretty much going to be at my discretion. Race size will be limited to around 50 participants. Suggestions?

http://www.gmap-pedometer.com/?r=855161

@3.4 km, I realize this is a bit large. Definitely want turns in both directions. Start/finish points at your discretion. Course is going to be basically pancake flat any way you look at it. Maybe I can name the course after you!

That first one is a death march. Not for the riders but for the spectators. Each lap would be more than 4 minutes.

The last one is really going to be rounded off.
Which direction? Did I miss that?

Direction doesn't matter. I think all of the ones shown so far are intended to be counter clockwise as depicted.

I think I like the first one KP did. Cutting out the southern-most section of the original keeping the big turns.

This course would keep the entire route in view of spectators, no buildings in the middle.

http://www.gmap-pedometer.com/?r=855385 (2 km)

Edited to add that the intersection in the middle of the "figure 8" is about 500 feet wide so overlapping riders in both directions would be no issue.

Me too, as there's a good mix of left and right turns. Although maybe you could move the start finish so that the final sprint doesn't end near a turn.

ahhhh... now you're getting creative. That's a nice one. The intersection that almost completes a figure 8 looks like a good place for photo opps and haybails.

Shortened out a corner or two. 1.7 km.

That's what I was thinking. The big 120deg corners on the top and bottom would give it a classic crit feel.

I actually like the first one. I guess you could call it a circuit race to justify the longer laps, but I think it's still spectator friendly because it comes back fairly close to the home stretch so they will see the pack twice per lap, plus the final corner is pretty decent for viewing.

Thekillerpenguin's crit with the "finishing stretch" is the best for a classic crit in my opinion, although you have to get the spectators to the runway instead of watching near where I assume they enter the area like your first one did.

I might add that I'm glad you didn't get too liberal with the free space you have. I did the first Jackpot Grand Prix in Las Vegas, and they got too excited about using a huge parking lot and made keyhole turns and sweeping corners, LOTs of them for a 1k course. It would have been better for autocross racing than bicycling. Oh, and I'm glad nobody here things 180 turns are a good idea. Too many courses around here have them because they could only close off 1 street!

yeah, it'd definitely be a fun course to ride, but like eventservices said it'd probably be pretty crappy for spectators.

As for the start/finish line, it could be moved to the that semi-long stretch on the left side of the course and would be made safer and faster that way.

I can't tell how much space they have, but if there's ample room and hay bails in between the 2 sections, it will work. Still not a spectator friendly course imo, but I don't know if the OP cares about that anyway.

I'm not too worried about spectators. Cycling isn't a huge attraction in the area and I wouldn't expect many more spectators than would arrive with the riders.

I think the final route will be the figure 8, but moving the start finish to here:

http://www.gmap-pedometer.com/?r=855766

Course will run clockwise. This will allow me to plan parking in the empty portion of the flightline to the left of the start/finish. It gives about 150 meters of finishing straight. It allows me spectator space in the grass to the west of the start/finish. It also allows me to use the same start/finish for both the North/South 5km time trial on the runway and parallel taxiway and the crit course.

Well, that was easy enough. Now for getting the rest of the leg work done.

(Oh yeah, I'll also have a good shot of the whole crit from the top of the air traffic control tower for video)

No, no, no. It needs to be a _true_ figure-8, with the paths crossing like when you smashed up your slot cars down in the basement as a kid.

_That_ would be spectator friendly.

By the way, is that plane going to be there on the tarmac? You could also liven things up by firing up the engines for a little cross-breeze now and then...

That's a DC-9 in the google image and would launch riders pretty nicely. Keeping that portion of the flight line clear will be another of the issues to work on in the next couple months.
