Not a ton of entries posted in the 10k men's and women's open races at this juncture. Hopefully the fields fill out in the next couple days. For the most part the armed forces' athletes seem to be signed up in their entirety but not many other professionals.
Below are just the names I recognized from the 52 women and 76 men confirmed:
Sarah Pease Oiselle
Paige Stoner Reebok Boston Track Club
Emmanuel Bor NIKE / U.S. Army
Hillary Bor U.S. Army
Michael Jordan NIKE / U.S. Army
Lawi Lalang NIKE / U.S. Army
Anthony Rotich NIKE / U.S. Army
