You can try doing this with a friend or two, and switch something like every 20 dodge or something. Dodge the lightning, then go back to where it strikes you, then it will strike you again immediately, dodge it and go back to the same place, then there will be a pause before it strikes you again. Dodge, then go back to the same place and it strikes you immediately etc etc... It keeps on repeating like this (quick, slow, quick, slow)
Saving doesn't help I think... You just have to do this without bailing or going to the next map/screen. It's tough I know, and I really hate it just like how you do.
I did it with my sister's boyfriend, and we bailed at about 180, then we did it right next time. It's annoying but you can do it. Just dodge some and take a break, and continue it.
