As of 3:42pm, the DEQ site (https://oraqi.deq.state.or.us/home/map) shows Portland at 157, while Beaverton is at 114. But, the DEQ data appears to be updated only hourly. The real-time data for Beaverton (http://aqicn.org/city/usa/oregon/beaverton/) indicates 85. Upon which data will you decide, Beaverton vs. Portland, real-time vs. hourly?

There will be no racing tonight unless AQI per Oregon DEQ drops below 100 by 4pm.
