Checkpoint. Another day in paradise weather-wise: Partly sunny to partly cloudy, cool but comfortable in the low to mid 60's, wind picked up in time for the return trip to 10-12 mph from the WSW. Lake County really knows how to do a trail and a Forest Preserve - trails in almost perfect condition. This area has some stunning views riding through Part 4 of 4 on the Des Plaines River valley up towards the headwaters in Wisconsin. The most beautiful area was around Sterling Lake and Van Patten Woods Forest Preserve up near the Northern trailhead which is just a few miles South of the Wisconsin border. I will definitely do this one again in the Spring or early Fall during peak leaf season. Tons of other bikers and hikers throughout the day. Good steady ride: I wasn't pushing the pace but ended up pretty good for a trail ride. Speed definitely slowed down on the return leg with head and crosswinds most of the ride. 4th day in a row riding, already up to 141 miles so far, expect to top 200 miles with a long road ride tomorrow.
