Training for first ultra

I am planning to run the Bimblers Bluff 50K in October. I have been running for six years. Unofficially ran a marathon stopped at mile 24. I have also run 27-28 miles on a training run before. I have started back into running after a four month hiatus.

My current mileage is 40 and want to peak at 60. My goal is to run Bear Mountain in May next year.

Two questions: I have a 24, 26, and a 34-mile run planned out up to September. These are going to be self-sustained do it yourself runs. Any tips? Second question following along with the first if all goes well through until March of next year want to tack out an 8-hour run. Any tips on that? The run would likely be March 31. One week after that I sign up for a half-marathon and then two weeks following that, I would sign up for a 50K race. They both will be training runs. Then three weeks from that would be Bear Mountain. Should that be okay?

One final question on cross training: I weight lift and use the stationary bike and elliptical. I am also looking to incorporate yoga into that regime. Would I need any tweaking on cross training? Any other Cross training exercises to incorporate.

Appreciate the response.
