Another contender is likely to be Jared Abuya, a native of Kenya who has been training in in Colorado. Abuya placed third in the 2011 CDR in 1:24:52 but did not run here last year.
Like Weiss, both Morseman and Capriolo hope to run as marathoners in the 2016 Olympics and say they've upgraded their conditioning over the last year.
Morseman, who finished one minute, 45 seconds behind Weiss here last year, has intensified his speed training this summer and expects to run better in today's race.
"I've never been as confident as I am right now,'' he said. "It's a whole different complex that I'm throwing out there to see how my body adapts.''
Capriolo, who placed more than four-and-a-half minutes behind Weiss, has been averaging more than 100 miles a week for more than a month - an increase over last summer's training.
"I'm in better shape than I was last year,'' said Capriolo. "I'd like to finish a little stronger this year.''
Last year's female winner, Esther Erb of Richmond, Va., also returns. She ran a 1:36:07 and placed eighth overall but admits she struggled on the hills.
"This year I will kind of forget about the hill and run up it as best I can,'' said Erb, who's also a 2016 Olympic aspirant. "The rest of the time I want to focus on pace because the rest of the course is flat.''
