We ran the Big Marvine Loop on Sunday, 9/12/22. It was 30 degrees when we started and almost 80 when we finished. This was a great loop. All of the climbing is in the first 8 miles, then there is a 3-4 mile section across the top that is marked by cairns. There is no trail there. The trail starts up again by the Oyster Lake and takes you down the other side. We had a great time!
