Tim Wagoneer

Tim Wagoneer, AKA "Lucho", the expert voice of "Ask The Ultrarunner".

Tim Wagoneer, formerly Luchinske, started running at the age of 10 and went on to multiple Kansas state track and field championships and was a two time All-American in college. He decided to drop out after two years and travel eventually settling in the US Virgin Islands where he lived for four years. Tired of the party lifestyle he quit smoking and entered his first triathlon and placed third. Four years later he placed 16th over-all at Ironman Hawaii and was the top amateur. 15 Ironmans later and Tim switched to just running. He ran 2:41 in his first marathon and then 2:30 in his second. Tim and his wife moved up to 8200ft altitude in the mountains and this led Tim to try ultrarunning. In his first race, a 50 mile trail race, he won and broke the course record. He then went on to place 6th at the Leadville 100 in his 4th ever ultra. Next year Tim is planning on racing the Leadman which is all but the 50 mile run in the Leadville race series. Tim is a full time endurance coach and works from home watching his 2 and 4 year old sons.
