Route Description for N 63rd St
Ride north on 63rd St, heading out of town through rural landscape with wide open views. Gently rolling hills will continue on for as far as the eye can see. After a short climb and an old church, you will have a quick downhill section to the junction of 63rd St and Nelson Rd.
Turn left onto Nelson Rd. heading west towards the mountains. A gradual climb will have you cycling past the NOAA Table Mountain Test Facility. After a slight jog in the road, you will arrive at the junction of Nelson Rd and US 36.
Take US 36 south to Neva Rd., then turn onto Neva Rd. heading east. After a couple of short, punchy climbs, you will enter a sharp right-hand turn followed by an immediate left-hand turn onto Niwot Rd. This is the “turn and burn” section of this ride with a slight downhill, where you can put it in the large chainring and catch a tail wind, as you pedal to a max speed for an all-out effort. Niwot Rd. will reconnect with 63rd St. at the stop sign. Turn right heading south on 63rd St to head back to Tom Watson Park.
