LA Marathon 2015: Updated Weather Forecast, Race Route Ahead of Historic Event

You've never sweat like this before.

Record temperatures are expected for the 2015 ASICS L.A. Marathon, and while one would normally sweat profusely while running 26 consecutive miles, the perspiration will be amplified exponentially on Sunday.

The heat certainly won't deter loyal runners from competing. As one of the most popular marathons in the country, the race continues to grow each year. March 15 will be the 30th installment, and Irene Moore of NBC Los Angeles writes that 26,000 competitors come to race each year. It's one of the largest races in the nation.

Given the potentially dangerous heat, staying up to date on the weather forecast and race route is imperative to ensuring a safe and successful race day. Below is everything you need to know at the start of the weekend.

This weekend is going to be a brutally hot one for the folks in Los Angeles. 

Weather.com indicates that Sunday's high should be around 89 degrees, with 20 percent humidity.

"Temperatures to start the marathon will be in the upper 60s and will quickly rise into the 80s by 10 a.m.," says Weather.com meteorologist Linda Lam.

"The record high temperatures for Sunday is 85 degrees set in 1978 and the record may be broken as temperatures are expected to be near 90."

Because most runners aren't used to covering 26 miles in that type of heat, the event-runners have taken the necessary precautions. They are listed below, courtesy of LAMarathon.com:

• Earlier start time at 6:55 a.m. PT
• Initiating wave starts to give runners more spacing and ample time to replenish at hydration stations
• All 24 aid stations have increased amounts of water and other liquids
• The start and finish lines will have "cooling buses"
• Misting stations, cold towels and ice are now available
• Finish line services have been extended
• Course clocks will display time of day, not race time, in order to keep runners aware of passing time
• Regular updates will also be given

These amendments to the initial plans show why the LA Marathon has such a long history of success. By taking care of its runners, the event continues to prosper year after year.

While most competitors are running with the intent to beat their personal bests, the race's official website is encouraging runners to move at a slower pace than normal in an effort to prevent overheating. An inherent benefit of this is that runners can take a more relaxing, touristy view of the many landmarks around the city.

The beautiful course is highlighted in the next section.

It's not uncommon for marathon courses to be configured so that one starts and finishes at the same spot. This loop-like course allows runners to see most of the sights of the host city but not all of the landmarks.

The city of Los Angeles is inviting its 26,000-plus guests to see everything there is to see on Sunday. Below are the landmarks highlighted during each mile of the race, courtesy of LAMarathon.com:

Each historical venue on this picturesque course deserves to shine brightly. But because the race is now starting earlier than expected, the first hour or so of the race won't be with the sun directly overhead. That's why the event planners have again done something wonderful:

An already incredible event will likely feel surreal for competitors now that the spotlights have been added on the course.
