I ride this trail 3-5 times a week when the weather is warm. It is split into 3 sections:
North, Colburn Rd. to 5th Ave.
Central, South St/Mountain Run Station to Headwaters Park
South, Headwaters Park to Swine Creek Reservation
I only do the Central portion, round trip for this is about 17 miles if you start at Mountain Run Station. The North & Central portions are split by having to go through downtown Chardon, I'd rather not deal with the traffic. The South portion has been recently added, I have not tried it yet, but the fact that it is not paved and open to horses makes me leery of going on it. I might wait until the rainy season is over to make sure it is at least dry before testing it out.
The Central trail is very good for all kinds of bikes. The trails is paved and very flat for the most part. Slight incline depending on where you are on the trail, nothing strenuous. Scenery is beautiful, depending on the time of day you will see wildlife like wild turkeys, deer, geese, turtles, rabbits & snakes (there was a sighting of a bear a couple of years ago, very strange seeing the sheriff's car on the trail warning users). There are 4 roads you will cross, not much traffic on any of them except the Mayfield Rd. crossing - there is a paving company here with trucks entering/exiting the facility on both sides of the road after a recent expansion. Not too bad but you need to be careful. You will go over 3 covered bridges if you do the full Central portion of the trail.
Users of the trail for the most part are easy to get along with, everyone seems to follow the trail rules. Be sure to announce passing. The only place it bunches up is at Mountain Run Station & Headwaters Park. At times families or people who have never been on the trail are all over the path, can't seem to get the concept of the painted center line. The only time this is really bad is on holidays and weekends between 11-3ish. Early morning/evening is the best time to ride the trail in my opinion. There are facilities (relatively clean for what they are) at Mountain Run Station and a water spout at South St. Mountain Run Station also has a pavilion & picnic tables, nice place to hang out after a ride. Make sure you bring a cell phone and/or basic repair kit, if you break down you will not be near anywhere depending on where you are on the trail.
Gen of a trail
It should be noted that the north section ends where a Lake County trail to the north continues for a ways to GIrdled Road (then there is a break where cyclists have to go on the road to connect with the remainder of the trail in Lake County).
The section of trail southeast of Chardon toward Middlefield is a lovely section of paved trail, passing though three covered bridges (new--constructed as part of the bike path). It is fairly level, though there is a mild grade back into Chardon. This trail is a real gem, passing through quiet wooded and marshy areas. I've seen deer and wild turkeys, along with the usual human traffic of cyclists, walkers, in-line skaters, parents with strollers, and occasionally local cross-country teams! That makes it sound busy, but depending on the time of day it can be a very peaceful, quiet ride.
