This race has some impressive veterans: Ian Maddieson, 75, of Albuquerque, NM, is going for his 16th finish. Founder Gordy Ainsleigh, 71, of Meadow Vista, CA, is going for his 23rd. Meghan Laws, 57, of Cool, CA, has 11 finishes to her name (and she’s fast).
Vancouver’s Ellie Greenwood set the latest women’s course record (16:47:19) in 2012. Timothy Olsen of Colorado holds the men’s record (14:46:44), also from 2012. Canadian Rob Krar won the race in 2014 and 2015. (None are running WSER this year.)

Runners must qualify with a previous 100-miler or approved 100K race before entering the highly competitive lottery.
Many road runners first became aware of Western States thanks to Dean Karnazes‘s 2006 book Ultramarathon Man. Karnazes, now 55, returns to the iconic race this year for (hopefully) his 12th belt buckle.
There are 12 Canadians entered in WSER this year.
Who will win?
The iRunFar site creates what it calls its Group Think predictions based on data from almost 1,600 participants.
In the women’s field, newcomer Courtney Dauwaulter, 33, of Golden, CO, ranked first in total prediction points, followed by Kaci Lickteig, 31, of Omaha, NE (who has four previous finishes, including the win in 2016) and Stephanie Violett, 34, of Bend, OR (who has three previous finishes, including the win in 2016).

Camille Herron, winner of last year’s Comrades Marathon in South Africa, was considered a strong contender, but was forced to withdraw due to injury.
2014 Westerns States 100 champion Stephanie Violett is back and seeking her 4th finish. Hear her thoughts on training, how she's evolved her race nutrition, and why this race draws her back. https://t.co/cYGDOzelzy #WS100 pic.twitter.com/9DHbbjGmjF

Ultrarunner and triathlete Ailsa Macdonald, 37, of St. Albert, AB (the only Canadian woman entered), ranked eighth in the voting on the iRunFar list. Macdonald won her very first 100-miler, last year’s Sinister 7 in the Alberta Rockies.

On the men’s side, Jim Walmsley, 28, of Flagstaff, AZ, ranks first, followed by Francois D’haene, 32, of St-Julien, France, and Tim Freriks, 27, of Flagstaff. Jared Hazen, who ranked fourth, has had to withdraw due to injury.
Third time's a charm for Jim Walmsley at the Western States 100? He's trained well, retooled his nutrition and gear, and says he'll try to run at 15-hour pace. Watch his pre-race interview: https://t.co/hK6O2QZ3B0 #WS100 pic.twitter.com/0vFR23gvCd
