About the sled dog component of the event:
Mac Johnson is fun event. It is a fund raiser for their wild life. Once the dogsleds have had a run everyone is free to use the trail.
The event is not a Mush Larose event. It’s a Wildlife Centre event that the training group provides volunteers for, and advertised through Mush Larose and the Wildlife Centre.
The trail is intended for cross-country skiing and very pretty, but tight in a several spots. It is well groomed and about 6 feet wide for the race. No hills to speak of, but definitely more challenging, tighter trail than Larose. A good skier would be fine, but I would worry about a mediocre skier with a fast or large dog. They might crash into a tree if they didn’t make some corners – some of the sledders have. Helmet definitely a good idea.
Skijorers are welcome, but we recommend skiing it by yourselves first, before deciding if you feel you can do it with your dog. It’s not a long course (nominally 5 km), so you could ski it at 10 am and them race it later, or just wait until after the race and try it then since it is open to the general public. Lots of mushers take out a second team afterward, so you would be sharing the trail.
