Link to Cue Sheets

You can access the route through the Ride With GPS website and app. The smartphone app can provide turn-by-turn directions. Registered participants should check their email inbox for more information including  .FIT and .TCX files for GPS route information. The .FIT files are ideal for Garmin Edge cycling GPS's and the .TCX file is great for just about any type of cycling GPS. However, technology can fail sometimes and the most reliable way to navigate is to use the cue sheets along with the electronic navigation. Cue sheets will be provided at registration, but they will not be laminated. If the weather looks rainy, it is recommend that you print your own ahead of time and "laminate" them by applying clear packing tape to the front/back/edges of each cue sheet. 


1. Even though this is a laid-back event: YOU ARE RESPONSIBLE FOR YOU. We will have very limited ability to bail you out if you have a bad experience out on the roads. Know how to fix a flat or at least ride with someone who does. Have a cell phone and a bail-out plan if your ride goes up in smoke.

2. Don't be a jerk. Be respectful to your fellow cyclists, the residents of Grinnell and the members of the rural community. Make everyone glad that you are here. 

3. Obey all traffic laws. 100% of the course will be open to vehicle traffic so don't become a hood ornament.

4. Stay to right hand side of the road at all times, especially when cresting a hill. Again, don't become a hood ornament. 

5. Each participant is considered to be on a private excursion and remains solely responsible for any accidents in which they might be involved. The event organizers accept no responsibility for participants becoming lost, injured or worse. 

6. Do not litter. 

7. We will use the honor system to recognize who successfully finished each loop following the prescribed route. If you must leave the route for any reason, then return to the route where you left off, or let the event organizers know that you are bailing. This is for your safety and for the integrity of the ride. 

8. This is a self-supported ride. Once the cyclists leave Grinnell, no outside support from friends or spectators is allowed. This is for the safety of the participants and spectators as we want minimize vehicle traffic on the course. If a participant needs to quit while out on the course, they may have their support person come and get them. Please contact the event organizer if this is the case so that we don't have to come look for you. 

9. E-bikes are welcome! Just remember that this isn't a race and be ready in case of battery malfunction. 

10. There are no official cut-off times for the 25 mile or 50 mile loops but all cyclists must be in by 7:00 PM (9.1 MPH average for those doing the full 100 miles).  This is so that we don't have to come looking for you and so you don't miss out on the live music. 

11. Cue cards and GPX files will be provided for navigation. Use both so you don't get lost out there.
