Minneapolis is bracing for an unusually warm weekend as the Medtronic Twin Cities Marathon approaches. While fall typically brings cooler temperatures, this year runners and spectators alike will need to prepare for heat and humidity.

Twin Cities Marathon Weather Forecast: Hot! Hot! Hot!

Saturday's forecast predicts a high of 90°F (32°C), potentially breaking a record set in 1922. Strong wind gusts of 30-40 mph will add to the discomfort. Sunday, the day of the marathon, will see morning lows near 70°F (21°C) and afternoon highs potentially reaching the low 80s (around 27°C) with lingering humidity.

Race Director Ed Wetham described the conditions as "less than ideal," issuing a "Code Yellow" advisory. However, all races are scheduled to proceed as planned.

Safety Precautions for Runners and Spectators

Organizers are taking extra precautions to ensure the safety of the 30,000+ participants expected across all events. These measures include increased hydration stations and medical personnel along the course.

Here are some tips for staying safe during the Twin Cities Marathon weekend:

Hydrate frequently: Drink plenty of water and sports drinks before, during, and after the race.
Pace yourself: Don't try to run faster than you're comfortable with.
Listen to your body: Pay attention to any signs of heat exhaustion or heat stroke, such as dizziness, nausea, or headache.
Wear appropriate clothing: Choose lightweight, breathable clothing that wicks away moisture.
Spectators: Find shade, stay hydrated, and be aware of the signs of heat-related illness in yourself and others.

The weekend includes a variety of events, including a Diaper Dash, Toddler Trot, half-mile and mile runs on Saturday, as well as a 5K and 10K. Sunday features the 10-mile race, the full marathon (26.2 miles), and the half-marathon.

While a stray shower can't be ruled out, the main concern is the heat. By Monday, temperatures are expected to drop significantly, returning to more typical early October conditions. So, enjoy the sunshine and warmth while it lasts, but be prepared for a hot Twin Cities Marathon weekend!
