Results from the Mendon Ponds Park Winterfest event are now available on the results page.


Next Sunday, January 17 is Winterfest at Mendon Ponds Park. As part of this celebration, the Rochester orienteering Club will sponsor an orienteering event starting at Hopkins Point Lodge. Since it is unlikely that we will have enough snow for ski or snowshoe, most likely we will have a Scatter-o on foot. There will be several courses, each requiring a different number of controls, to be taken in any order. There will also be a normal white course (controls in a specified order, all on trails.) Winterfest starts at 11:00, as does our registration. Starts from noon to 2:00 pm. Winterfest also offers many other attractions if you have extra time!

Use Online Registration to save time at check in and insure yourself a map.


Annual Meeting and Potluck Dinner
Sunday December 6th
Stewert Lodge, Mendon Ponds Park

1:30 - 3:00 BOD Meeting
3:00 - 4:30 Events*
4:45 - 5:15 Pot-Luck Dinner
5:15 - 5:30 Annual Meeting (All club members welcome)

Trail O is a little different from standard courses. You walk/run to a location (on a trail) and from that vantage point you must look and pick the control that is described/shown on your map. There will be 3 controls visible and as you look from left to right you pick one of the controls A, B, C or none of them as the control shown on the map and described in the control description. The course is around 3km but you can do as many or as few controls as time permits.

A twist on the usual favorite. Instead of a rectangle grid shape it will be a triangle. Challenge your spacial skills to read the map fast. There will be different levels of difficulty, so fun for the whole family!

*This is a member only event (FREE) (if you aren't a member, join when you arrive! It is only $15 for an individual and $30 for a family. You membership will be good to March 2017)

Don't forget your potluck dish to pass and bring your own utensils and dishes. The club will provide drinks. Based on your last name please bring the following type of dish so we don't end up with all desserts (although I wouldn't complain):
A-H (Appetizers), I-P (Main Courses), Q-Z (Desserts)

See you there!
The Worner/Kohn Family

Orange - 13 controls, 4.6km, 120m

The trails were in good shape prior to this weekend's rain. With a dry week ahead conditions should be great for Saturday!

Reminder: You MUST stay on the trail in the Washington Grove section of the park. This area is notated on the map with a boundary box and a note to this effect. Additionally, the Monroe County Water Authority property is marked Out Of Bounds per their request (also notated on the map).


Results from the Letchworth State Park East event are now available on the results page.


Letchworth State Park event on Saturday, September 12. which will start on the East Side at the Parade Grounds, no charge for entering the park.

Starts from 11-1pm, courses closing at 3:30.

White 1.9km 70m climb
Yellow 2.5 km 80m climb
Brown 3.8km 140m climb
Green 4.4 km 150m climb
Red 5.5 km 270m climb

The woods are generally very dry due to lack of rain. Crossable marshes and ponds are dry and special attention to locate or use as navigational aids will be required. Springs are still active, making most streams easy to locate.

The West side of the park near the Glen Iris Inn should be avoided between 11:30 and 1. There is a 5k race that closes the roads from the Castile entrance to the Trout Pond. This shouldn't affect anyone unless they decide to take a scenic route through the West side of the park.


ROC had a great presence at the Lehigh Valley Festival in Mendon. There were many outdoor clubs there as well as arts and crafts, a bicycle ride, a half-marathon, and many music performances. ROC’s booth was on the sidewalk and we were very busy answering questions about orienteering as few people knew anything about the sport. We had a map adventure including controls on historical buildings as well as interesting spots on the trail, one a cow tunnel for cows to go under the railroad track. The profits from this event supported the Mendon Foundation which maintains 14 miles on the linear trail from Mendon to Rush and the Genesee River.

Volunteers included Anne Schwartz, Tom Cornell, Carol Moran, Lori Rayburn, Sheryl Zenzen, Nancy, Richard and Daniel Burgey, and Sandra Lomker.

Participants who negotiated the Map Adventure were Tabetha Besanceney, Anne Schwartz, Chester & Gregory Doskos, and the Burgey family (Nancy, Richard, & Daniel)

Next event at Mendon Ponds Park.

There will be a 1.8 km (approximate) White course, a 2.0 km (approximate) Sprint course, and a 60-minute Score-O. The White and Sprint courses start any time between noon and 2 pm, with the courses closing at 3 pm. The Score-O will be a mass start at 1:30, with the course closing at 2:30.

The start location is the Pond View Shelter, reached via the middle entrance to the park off of Clover Street.

Always in need of volunteers, use the link on side menu to see what positions still need to be filled. Helpful when we can get the positions all covered well before each meet. Please contact Sandra if you can help out.

Results from the Genesee Valley Park event are now available on the results page.


There will be an orienteering event this Sunday, April 26 starting at the Roundhouse shelter in Genesee Valley Park.

A white course and 2 sprint courses will be offered by course setter Mike Lyons. The white course is beginner level. The sprint courses are short in length and mostly in open terrain, to challenge competitive runners to move and make decisions quickly. But they can still be challenging to those not up to sprinting! Starts are from 12 to 2 PM. Please use the Online Registration link on the side for the event or register at the event.

We will be offering two Sprint courses and a White course on Sunday – all are variations on the courses that were used for the US Nationals last fall. The Red Sprint is 2.8k and 19 controls, the Orange Sprint is 2.1k and 15 controls and the White course is 1.9k and 13 controls. All of the courses cross one or more park roads; despite the low posted speed limit and likely light traffic, participants should exercise caution when crossing.
