Start to 1K – From the Visitors center head north on the wide grass trail for the first 400m, crossing the road at 400m. Continue on the wide grass trail to 800m through open fields. From 800m to 1,000m the trail is wide dirt in the forest. The 1K mark is just after the first trail junction in the woods. The first Kilometer climbs 90’ and drops just once (15’).
1K to 2K – From the one Kilometer mark continue East on the dirt forest trail which bears South to the 1500m mark. The race course continues turning East on the wide grass trail under the power line. This Kilometer climbs 110’ with no measurable drops. The 2K mark is just after the small snowshoe trail on the right.
2K to 3K – Continue from the 2K mark 200m further on the power line trail then bear right into the woods on a wide dirt forest trail. The 3K mark is 150m after the second major trail junction. There is one slight 20’ dip at 2.5K; otherwise this Kilometer climbs for a total of 150’.
3K to 4K – Continue climbing on the forest trail, and turn South at 3.5K. Continue to climb to the 4K mark which is 250m before the road crossing. There is one slight down hill at 3.6K, otherwise this is the toughest Kilometer with 325’ of climb.
4K to 5K – The wide forest trail begins to bear west and continues Westerly to the 5K mark which is 100m before the minor trail junction (which leads to the summit road). This Kilometer has two down hills one minor drop at 4K of 20’ and another from 4.5 to 4.8 K where it drops 85’. Other than the two down hills, the course climbs steadily for at total of 180’.
5K to 6K – After 5K the trail begins to turn south and has two small drops of 15’ and 2 small climbs of 15’. The course turns East at 5.7K and climbs the final 300m, crossing the summit road and heading to the viewing platform. It climbs 200’ to 5.9K. The final 100m to the viewing platform drops 35’. The 6K mark is at the viewing platform overlooking the man-made lake on the summit of Northfield Mountain. A water stop will be available at the viewing platform.
6K to 7K – The runners retrace their steps for 300m, going West over the summit road and down the forest trail. At 6.3K they turn South on the wide grassy forest trail. The course bears Southwest and forks left. This Kilometer is mostly downhill with a short climb of 35’ from the viewing platform to the road and another 10’ climb 700m later. The total downhill running for this Kilometer is 115’. ; The 7K mark is at the minor trail junction just after branching to the Southwest.
7K to 8K – Continue Southwest with a major Western bend at 7.8K. The trail is wide and grassy and there are a few rolling hills despite an overall downhill run. 8K is 150m before the major trail junction. There are four small up hills of 15’ each spread out evenly through this Kilometer. The last 300m features a steep 120’ downhill. The total for this Kilometer is 285’ of descending.
8K to 9K – The race continues West on the forest trail, turning North @ 8.5k on the wide grassy power line trail. 9K is located at the stream crossing, 250m after the major trail junction. This Kilometer is all downhill, steadily dropping for a total of 330’.
9K to 10K – This entire kilometer is a straight run north down the power line on a wide grass trail. There are three up hills mixed in this predominately down hill Kilometer. The first two are “bumps” of 10’ and the final one is a tough uphill climb of 30’ starting at 9.8K. The 10K mark is at the end of the power line section, just prior to turning west. The total for this Kilometer is 160’ of down hill running.
10K to 10.3K – The final 300m of the race heads West down the wide grass trail and then turns north for the final 100m. The finish is located in the field behind the visitor’s center, which is the same location as the start. The 200m downhill drops 115’ and the final 100m is flat.
