Too bad we're not in the same geographic area. I'm in the same boat generally. It's tough to find compatible riders with compatible schedules. Best of luck to you. Sometimes local shops have group rides where you might meet potential riding buddies.
Have you tried meetups? There's one for Jeffco mtb. I was part of it for a few rides but did not find the group particularly friendly, however that's just my impression.I have been back on my bike for almost a year now after 15 years off the bike. I have 120/120 Intense 951 XC and just bought a Ripmo AF. I ride 3 times a week when trails are dry, from Centennial COne to Buff Creek to White Ranch (Longhorn), Apex, Mt Falcon, rode Hard money on 120/120 and cant wait to try my Ripmo AF there.
Also want to try Floyd Hill, ride Walker Ranch again after 20 years away. Hall Ranch and Cub Creek are on my list this year as well.
I like riding alone but sometimes miss the group rides, I know no one here that I can ride with. I would like to meet some people and see if we do some riding together.
I like to climb and suffer but need to lose 15 lbs or so to be better at it, I can hold my own on downs, wont win any enduro races though.
I am 50 yrs old and live near Golden and have a flexible schedule most weeks, I am a contractor so one week ish a month I have little to no time then other weeks wide open.
