If you are going from Abq to Denver, there are more fun routes than I25. Although, in a month or so parts of the route will be snowy, so... The up side is Colorado has some great highway monitoring going on, so you can check on road conditions right from your phone.
The 'fun' route is to take highway 550 towards Farmington just north of Albuquerque, and then turn right onto state 4 to Jemez Springs. This will take you over the Jemez, lots of twisties, and a caldera to view. Once you come over the mountain, you end up in Los Alamos. Wave at me as you go by. Head out on 502 and take the exit north to Espanola. From there you can go up towards Taos and enjoy the twisties in the Rio Grande Gorge there. From there, you can head up north into Colorado, and either head to Walsenburg and pop back onto I25 about an hour south of Colorado Springs, or follow 285 north and enjoy the various twisties and passes up to the interstate (i'd recommend going through Leadville, taking highway 91 to the interstate). Stop in Dillon and find the Dillon Dam Brewery for some good food and brews. Then, head toward Denver. If you have time, I'd also recommend getting off the interstate and taking highway 6, which is a wacky left exit a few miles past the Eisenhower Tunnel, and having a blast with that road and its 5 tunnels into Golden.
Orrrr you can take the interstate and save yourself probably 2 hours, as you enjoy the gentle bends as you drone on through Raton, and the crazy Colorado drivers and their utter lack of cruise control (yeah yeah its subjective
If you feel like a slight detour, drop me a line, and I'll join you for most of this stretch
