He is co-founder of the Worlds End Ultras, Logistics Director for Eastern States 100, and co-founder of the Eastern States Trail-Endurance Alliance.  He’s run 50 trail races, including nearly 30 ultras.

Benjamin J. Mazur has been very active in the "Rocksylvania" running community. Nine years ago, Benjamin was a founding member and now serves as current president of Allegheny Trailrunners, Inc. - a 501c3, all-volunteer not-for-profit, that organizes a series of trail races as an advocate for trail development throughout the Alleghenies. Benjamin has directed almost two dozen trail events including Rock 'N The Knob and Dirty Kiln, and also served as co-director, volunteer coordinator and/or as logistical support for Worlds End, Eastern States and Black Forest ultramarathons. If he is not working at those races, you can find him volunteering, or cheering on at dozens of other trail events, or at a brewpub or tavern enjoying an IPA.




Thad Will’s trail running roots started with the Nittany Valley Hash House Harriers, a social running club in the State College area that values the recuperative effect of beer to the body and soul of its members. As such, it was only a natural transition for Thad to the central PA trail running community in 2009. Thad completed his first ultra at Hyner in 2014. Since then he’s completed multiple ultras at  every distance up to 100 miles, including Worlds End, Laurel Highlands, Massanutten, and Eastern States. Thad lives in State College with his understanding wife Ellen, and boys Jacob and Nate. 




George Conrad is new to the sport of trailrunning, yet he has participated in an impressive roster of trail races up and down the East Coast, from Twisted Branch 100K in New York, Oil Creek 100 and Worlds Ends 100k in PA, to Eastern Divide Ultra and Grindstone 100 in Virginia. He completed Eastern States 100 in 2019.

George currently serves as President of The Standing Stone Trail Club, who are the stewards of the 80-mile long main trail network with side trails located in the ridge-and-valley Appalachians of Central Pennsylvania.  He brings his skills and talents in grassroots advocacy and conservation to ESTEA.

George is proud to call Huntingdon County in Pennsylvania his home turf. 




Originally an avid equestrian, Cassandra Lizza gradually turned in her riding boots for running shoes as she discovered the sport of trail running. With a love of rugged, tough, and remote trail events, she found herself drawn to the Pennsylvania Wilds region. She ran her first ultra at the inaugural Hyner Trail Challenge 50K and has since completed multiple ultra events around the region—including Eastern States and the PA Triple Crown in 2016. She has participated in Eastern States every year that it was officially held since its inception, starting with crew and pacer to volunteer. A New Jersey native who now calls Lancaster City home, Cassandra can often be found exploring trails in Michaux, Tuscarora, and Bald Eagle State Forests.




Jade is a life-long Pine “Cricker” who was running around the Rocksylvania mountains before she even knew trail running was a thing. Running her first trail race at the original Call of the Wilds, she discovered other people who like to hide in the woods for hours on end as much as she does. More of a hard ass than a bad ass, she’s likely to tell you to quit whining and run. But, she’s married to a Canadian, so she’ll probably apologize to you for it, too. Jade served as co-Race Director for Eastern States 100 in 2019, and she's excited to not only serve on the ESTEA board, but also to step into the Eastern States 100 Race Director role for 2020.

He also moonlights as a writer with contributions to and articles published in Like the Wind, Trail Runner and

Tom was born and raised in Williamsport, PA.  During the normal work week you’ll find him at work with PA’s Department of Environmental Protection where he is a Professional Geologist, charged with protecting the Commonwealth’s environment. Tom got into trail running in 2010 as a way to get into shape.  He ran at the inaugural year of the Hyner 50k, and since has been hooked on ultrarunning. He has traveled to various ultras up and down the East Coast from the New York Catskills to the Georgia mountains but has found that trail running in Pennsylvania is the best; from the courses, to the volunteers and the overall positive attitude in the Pennsylvania trailrunning community.  Tom truly believes in giving back to this community, which is why you will most likely see Tom volunteering in some capacity at ultramarathons in Central Pennsylvania.
