Both are around 1300 miles (300 miles further than I-15 thru UT)
Good low altitude route and you can cut a few more hills out by staying on 1-10 to US 70 in Las Cruces then over to US54 in Alamagordo and up to NM 3 at Duran then up to I-25. There is some construction on US 54 and 3 runs along the Pecos River for 15 or so miles with a reduced speed, but they are good two lane roads without any significant grades. The 70/54/3 route misses the 7500ft of Glorieta pass, although eventually you have to climb up to Raton at 7835ft. NM 3 goes past Villenuava State Park if you are a trout fisherman.
