C&O Canal 100

Knoxville, MD 100 Miler

This Event Took Place Sat. Apr 24, 2021

2021 Update

On 2/25/2021 the NPS approved our outstanding permit for the spring race!

The largest obstacle to having the race in April will be finding plenty of volunteers. To be able to have the event in April we will rely on support from runners to find new volunteers/aid station captains. If we cannot find enough volunteers some aid stations may need to me made minimal aid/water only or the race may need to be pushed back to the August 28-29 “rain date”. A link to sign up as a volunteer will open on Ultrasignup with official registration.

The COVID mitigation plan will not allow crew access at the normal Brunswick aid station to limit crowding on the canal. The current plan will allow crew access at Manidokan, but this is subject to change. The current plan will allow only one pacer starting at mile 69 to the finish and they must start/stop at Manidokan since there will be no crew access elsewhere on the course. The simplest way to guarantee you can see friends/family out on course may be to have them work at an aid station.

The current COVID mitigation plan can be found below and the overall COVID mitigation plan is subject to change based on local, state, and federal guidance.

1. Packet pickup of race bib will be cancelled for 2021 and they will be mailed to runners in advance of the event. Premiums will be picked up after finishing. Pre-race briefing information will be recorded in a video/email and sent to runners prior to race morning. This will eliminate crowding and congregating on race morning.

2. Participants (runners and pacers) will have to print and bring a signed waiver stating that to their knowledge they have no COVID-19 symptoms AND they have taken and received a negative COVID-19 test within 72 hours of the event or been fully vaccinated (2 weeks after Moderna/Pfizer second dose or 2 weeks after J&J single dose). Volunteers will be strongly encouraged to take and receive a negative COVID-19 test in the 72 hours prior to the event and will be required to wear a face mask at ALL TIMES during the event.

3. Runners will start in waves of 10-50 people, socially distanced, every 2-5 minutes starting at 7:00AM on April 24th based on the latest guidance from local, state, and federal health authorities on group size limits.

4. Runners will always be required to wear a face covering when social distancing (> 6 feet)is not possible (e.g. race start/finish, aid stations, passing another runner, passing another C&O Canal user).

5. All race volunteers will be required to wear face coverings and those handling foods will wear disposable gloves.

6. Runners will be required to use hand sanitizer prior to entering an aid station. Aid stations will be organized so that race volunteers will dispense all fluids/food items to runners upon request in disposable bags/cups, etc. Aid stations will be organized so that social distancing is possible. Pre-packaged food items will be prioritized for safety.

7. Spectators will not be allowed at aid stations. Each runner will only be allowed ONE crewmember at the Manidokan (not C&O Canal) aid stations. Runners will be allowed only ONE pacer and both runner/pacers must wear a face covering or be socially distant.

8. Runners will be discouraged from spitting, coughing, or sneezing without properly covering mouth and nose.

9. Handwashing/hand sanitizer will be available at all toilet facilities ad face coverings will be required inside all toilet facilities.

10. Pre-race meal cancelled. Post-race meal changes TBD.


The C&O Canal 100 mile race will feature one ~40 mile loop and two ~30 mile loops almost entirely on the C&O Canal towpath starting at Camp Manidokan and running along the canal between Antietam, MD and Brunswick, MD. The C&O Canal 100 course is almost entirely flat and offers plenty of opportunities for new 100 mile runners and old veterans who are up for a challenge on a beautiful course.

There will be approximately 7 aid stations placed throughout each loop, some of which you will encounter multiple times. The distances between aid stations range from 3-6.9 miles. See the websitefor a more detailed course description and the official course map

The 2021 race will be held on April 24-25, 2021, starting at 7AM on April 24th, 2021. Registration will open on December 16th, 2020 at 7AM EST.

Credit cards will not be charged until the COVID plan, permits, sanctions, and insurance have been finalized.
