I am generally on one section of this trail or another every Sunday. It has been a treat to ride off road on a designated trail for bikers and walkers. From where I live, it's all downhill going from Sahara/Charleston area to Trop. On the way back, it's uphill, but it's an easy grade so there's no huge amount of exertion.
There are two street crossings that you need to do with care--Flamingo and Fort Apache. Other than that, there are underpasses at Hualapai and Desert Inn and a new overpass (built and opened this year) over Town Center Drive. The crossing at Sahara and the 215 is generally a quieter spot but take care nonetheless.
I am pleased to see the increasing numbers of people who use the trail for jogging, walking, and biking. Now, if they would only continue it north beyond Charleston as there are plans to do, it would be great. Funding from SNPLMA (Southern Nevada Public Lands Management Act) has almost all dried up, so future expansion will take time.
It is nice to see the County in general is building trails that will connect so we could conceivably ride to the east side of town from Summerlin with a minimum amount of on street riding.
