Are you going to race it or participate in it? 3 weeks out is typically your last big weekend before you ease off the gas. It is usually nice to have pacing and nutrition figured out before that and tested earlier in the cycle (10 weeks out). That last weekend might be similar but it typically isn't back to back to back at race effort and pacing.

Will you see gains? Probably. Will your performance suffer in CdA? Maybe but you have plenty of time to recover. If you plan to pace it as a nice, supported training day, go for it. Would I race it? Not personally but that also depends on your CdA goals.

Will this thread give you numerous different opinions? Most definitely :)

I'd do it. That is a tough race in Kansas and will be hot. It will make you a man. You have plenty of time to recover. I did it last year. The next week I won a local oly. Then the week after that, I pr'd with a 2:48 marathon :). The last 2 races seemed so easy compared to legend 100
