HVO/WCOC Winter Series

2020 / 2021

Once again, HVO and WCOC are pleased to host a series of eight bare-bones, time-yourself orienteering races this winter. As with last year, each event offers a Brown, Green and Red course, and participants download the maps from a link posted on HVO’s website. Control flags will be out in the woods for about four weeks and the events overlap some weekends so you can do two in one day/weekend if you want. You run whenever you want while the flags are out. The races are honor system based with no boxes/punches on the controls, just touch the flag (no remote visual punching). No beginner’s courses will be available.

When and Where

In case of major snow falls, revised dates may be considered and posted.

Maps will be available for downloading on HVO’s website the day before the controls are in the woods.

Results and Ranking
Participants time themselves and subsequently upload their results directly to the respective Attackpoint.org event pages. Posting splits and GPS tracks are preferred, but not required. Participants can also upload tracks to Route Gadget.

Each participant in any or all of the Winter Series events assumes full responsibility for any and all injuries, losses and damages that he or she incurs while attending or participating in the Winter Series event.  Downloading of any map constitutes agreement to the waiver which is available on the download site.
