Spent the 1970's and 80's marathoning.  Transitioned to ultra-distance (running, snowshoeing, cycling) in the 1990's.  Caught the adventure racing boom and raced 6 Eco-Challenges. Retired to Alaska-based ultra-distance races (Susitna 100, Iditarod Invitational, Yukon River Quest) and some 24-hour mountain bike racing.  Just qualified for this year's edition of Paris-Brest-Paris.
