I wandered over that way one before while scouting, and got caught up in all sorts of mess, so there was no way I was messing with it!
When I left trail near lake, first 200m at the water's edge were very runnable, some sand and stones, but after lake was deeper and shore more hilly. I had a choice - running 150-200m in water or return and crossing woods and swamp (really it was shallow pond, not swamp). I chose to return.
The map needs some updates. Lots of trails in that area.
Thanks for coming Oleg and Igor, thanks for updating the map! Can't wait to see it!
