We present modeling and experimental results concerning the guiding of relativistically intense laser pulses with peak power of 0.85 PW over a distance of 15 diffraction lengths. Laser guiding was achieved by increasing the focusing strength of a capillary discharge waveguide using laser inverse Bremsstrahlung heating. This allowed for the production of electron beams in a laser-plasma accelerator with quasi-monoenergetic peaks up to 7.8 GeV, double the energy that was previously demonstrated. Charge was 5 pC at 7.8 GeV and up to 62 pC in 6 GeV peaks, and typical beam divergence was 0.2 mrad.
