As a member of the Road Runners Club of America (RRCA), we follow their guidelines on headset use.  RRCA does not encourage headphone use during its member races but does not disallow them as long as they are used safely. For this reason, Oil Creek 100 Trail Runs will allow headphones on the course only if it does not pose a safety risk.  If you absolutely must use them KEEP THE VOLUME DOWN so you can hear runners approaching from behind - or risk getting run over in wild & tough 1860's oil boom era fashion.  For safety reasons, it may be necessary for a course official to ask you to remove your headset/earphones during the race. You are required to comply or face disqualification and removal from the course.

Benninghoff Farm today - the 35' replica oil derricks are the inspiration for the logo and finisher's award buckle.  All runners will pass them on their way from Wolfkiel Run AS #1 to Egbert Farm AS #2 in Petroleum Center :

NOTE: in 2021 we removed the date from the front - due to COVID-19 pandemic cancellation concerns - and put the distance instead

The wild & tough 1860's oil boom era in Petroleum Center where crew-accessible aid station # 2 is located (Egbert Farm picnic pavilion).  Washington Street is now Petroleum Center Road - notice the faint outline of the hill in the background for the then / now photo below:

Washington Street then, Petroleum Center Road now.  Benninghoff Farm is only about 1/2 mile down this road (toward Titusville) where the OC&T railroad tracks & train tressel are located:

Benninghoff Farm today - from the east Gerard hiking trail scenic overlook.  The paved road you see in this photo is Petroleum Center Rd (the old Washington Street) that is used to access Petroleum Center's Egbert Farm aid station # 2.  This overlook is on the official course - it is beautiful with the October fall colors - and 100 mile participants will get to see the derricks illuminated Sat. night / Sun. morning
