The International Ski Federation Alpine Ski World Cup arrives in Beaver Creek, Colorado this weekend for its annual Xfinity Birds of Prey races.

How it works: Think of the Alpine Ski World Cup like the PGA Tour, but for skiing. Each weekend during the winter, the world's best skiers travel to venues all over the globe.

  • Tour stops: After opening races in Austria and Finland, the men's tour goes to Lake Louise, Alberta around Thanksgiving, while the women's tour goes to Killington, Vermont. Then the men come to Beaver Creek and the women go to Lake Louise. After this, they'll be in Europe for the rest of the season.

Disciplines: Downhill and super-G are speed events, while slalom and giant slalom are technical.

  • Downhill: Longest course, fewest gates, highest vertical drop. You get one run.
  • Slalom: Gates are closer together than any other discipline, requiring skiers to zig and zag quickly. You get two runs.
  • Giant slalom: Gates are spaced farther apart than in slalom but not as far as in super-G. You get two runs.
  • Super-G: Gates are spaced the furthest apart, and because its a speed event, it has a higher vertical drop than the slalom or giant slalom. You get one run.

Joe Biden's campaign released his 2019 tax returns on Tuesday, showing that he and his wife, Jill, paid nearly $300,000 in federal taxes last year.

Why it matters: The release, timed just hours before the first presidential debate, comes days after a bombshell New York Times report said that President Trump paid only $750 in federal taxes in 2016 and 2017. Biden's team is hoping to make the tax contrast a sticking point during their showdown.

New York City's coronavirus positivity rate has ticked up to 3.25%, its highest since June, Mayor Bill de Blasio said at a news conference on Tuesday.

Why it matters: The jump — from 1.93% on Monday — came on the first day that public elementary classrooms reopened in the city after months of closures, but guidelines state that all public schools will have to shut if the citywide seven-day positivity rate stays above 3%.
