Athletes at the Tokyo Olympics have been suffering from high temperatures and humidity in the opening week, but that will all change on Tuesday with the arrival of Typhoon Nepartak.

The typhoon is expected to make landfall during the women's mountain bike competition in Izu, but American Haley Batten said she "embraces the disruption."

The 22-year-old Batten, a two-time MTB World Cup medalist this season, is one of Tuesday's medal contenders. The storm was unexpected when Team USA trained on this course over the past week, but Batten is taking the forecast in stride.

"Typhoons definitely throw curveballs. We are not training for a specific scenario. We are training our adaptability and training our minds to be able to handle it as well," Batten said.

"It definitely makes the event more exciting.

The Japan Meteorological Agency is predicting 120 mm (4.7 inches) of rain and strong winds around Izu, but the worst of the storm is expected north of Tokyo.

This rain will make an already difficult course even trickier.

"It's a very tough course for the racers, with technical, fast climbs, uphills and downhills. I ran the course for a few days and really enjoyed it," Batten said.

"As you can see from everyone's pictures on Instagram, there are insane rock gardens and big features. It's very easy to get on and flows well."

"It's very easy to get on and flows well.

Batten, who won silver in Nove Mesto and bronze in Albstadt earlier in the season, is ambitious and confident heading into Tuesday's race.

"Earlier in the season, I surprised myself by racing for the podium. That motivated me and gave me a glimpse of what I am capable of.

"The Olympics are definitely a performance and a race for a medal.
