Travel the Boston Marathon route in this timelapse

Travel the Boston Marathon route through Hopkinton, Ashland, Framingham, Natick, Wellesley, Newton, Brookline and Boston.

With temperatures in the mid-40s and and no rain in sight, it's looking like it's going to be a beautiful race day for the 128th Boston Marathon this morning.

After an inconsistent spring of sleet, rain and cold, today is expected to be mostly sunny according to the National Weather Service, with a near high of 67 degrees.  

In the morning, when the race begins, the temperature is expected to be around 50 degrees, hitting that high temperature of 67 in the midafternoon. 

While this is great news for the people watching, those running in the marathon itself might not be as thrilled.  

Hotter weather has been found to worsen runners’ performance. Marathon runners tend to favor cooler temperatures and cloudy skies, as those conditions minimize the risk of heat exhaustion.  

Runners will have to fight through that midafternoon temperature high if they want to finish well.  

Here are the start times for the different groups.  

• Military March: 6 a.m. 
• Men’s Wheelchair: 9:02 a.m. 
• Women’s Wheelchair: 9:05 a.m. 
• Handcycles and Duos: 9:30 a.m. 
• Professional Men: 9:37 a.m. 
• Professional Women: 9:47 a.m. 
• Para Athletics Division: 9:50 a.m. 
• Rest of Field Rolling Start Begins: 10 a.m. 
• Rest of Field Rolling Start Ends: 11:15 a.m. 

This is the 100th anniversary of the Boston Marathon starting in Hopkinton. When the Marathon was founded in 1897, runners started from Metcalf’s Mill in Ashland, but the starting line was moved to Hopkinton in 1924.
