RRC is my favourite training loop in LV, about 15 miles short, with 1425 ft of climbing. I start my ride in Summerlin, LV, and head thru the desert to the canyon.
day 1 I do one loop, to acclimate and to get used to the elevation, day 2 two loops, day 3 three loops, day 4 is my recovery day, day 5 I usually do 3 loops again ... but next time I'll try four loops ... it will be my Mallorca preparation for 2019 usually we stay between five and seven days in LV, most likely in Airbnb's in the Summerlin area or at the Plaza Hotel in downtown, because it's close to the action, Freemont Street, and close to the freeways … 30 minutes to the RRC, the Valley of Fire, to Mt Charleston or Boulder City with its bicycle trails. … btw: no off road cycling/-biking in the RRC.
