Downtown traffic alert
High school cross country runners will take over the west end of the park strip for the Skinny Raven Urban Race, a giant block party disguised as a race. No need for drivers to worry -- the 3-kilometer race won't spill onto city streets or sidewalks. Australia's Benita Willis, the 2004 world cross country champion, will be there to sign autographs. 4-7 p.m., Delaney Park Strip.
A milestone mile?
Trevor Dunbar became the first Alaskan to break the four-minute mile barrier two months, but he did it in Portland. No one has ever run a mile that fast in Alaska, although Dunbar and others have tried. Now Jack Bolas, a New Balance-sponsored runner from North Carolina, will take a shot. Serving as rabbits will be UAA coach Tony Tomsich and Indiana runner Danny Stockberger, another New Balance runner. 4:30 p.m., The Dome (but get there around 4 if you want to watch -- the place fills up fast).
A Special weekend
The Special Olympics are this weekend, with two days of action at Anchorage Golf Course and the AT&T Sports Pavilion. Things kick off at 9 a.m. with opening ceremonies at the AT&T Sports Pavilion.
Beware, Seahawks fans
If you're headed to Seattle for Sunday's San Francisco game, a word of advice: Don't pick a fight with anyone in 49ers gear. Undercover cops will dress like San Francisco fans and sit in the stands, ready to respond to unruly behavior. The Seahawks organization said it's using the cops with the goal of ensuring a safe environment for all fans, even the ones rooting for the wrong team. 4:30 p.m., NBC (channel 2).
Steelers vs. Bengals
Pittsburgh's offense was MIA in the season-opener against Tennessee, making this something akin to a must-win game for the Steelers. 4:40 p.m., ESPN (channel 34).
Calling all Munchkins
The second race in the popular Tuesday Night Race Series returns to Kincaid Park. Race in the munchkin (1-3 kilometers), farm (3-10 kilometers) or lightning league (4-12 kilometers). Register from 5:30-6:10, race at 6:30 p.m.
