Review
This route exists in exact contrast to doing 3 lakes. This is the easiest way I can prescribe in good faith for doing 10 miles. This route is flat, easy, and comes with a pretty convenient water break.
The main reason for this route's existence is the fact that it comes with minimal elevation. Now, you can do less elevation and still receive 10 miles. For instance, doing 6 Top Loops would get you the necessary distance, but I don’t think doing one loop 6 times qualifies as a very fun route. Doing the Cashin + 2 Tops is a completely legitimate way to do 10 miles in my book though. The only necessary hill is the negligible part of Lake Hill that comes with a Cashin Loop, and after that point the route is nearly perfectly flat.
Also, you receive the benefit of a water break at 6.5 miles instead of 5. This comes in especially handy if you are in the belief of taking a bodily relief break at 3 miles, which is a common concept on long easy runs with my group of runners at least. By 6.5 miles the water that you have (hopefully) drunk throughout the day will be beginning to fade. Fortunately, you have the benefit of a nice water break before the final part of this run.
If the mediocre elevation of a 5 and 5 feels too much for you, then take it easy on a Cashin + 2 Tops.
