GazOC: I didn't follow the suggested hill training - I was nursing a hamstring tendon by slowing down while still upping the miles, so I wasn't going to put it under stress by doing hills! I used that schedule more for the mileage pattern, particularly because at the beginning I couldn't follow the Ultraladies 50K suggested weekend long runs because I couldn't run that far yet - the Run for the Toad schedule gave a more gradual build up. I later switched more to the other schedule.
I did recce runs along the route of the ultras I was training for, which gave me some training on that terrain, and my club's Wednesday and Sunday runs tend to be fairly undulating, and my parkrun course has a locally-infamous hill to run up - twice. During the next nine months I'm going to have to put in a lot of hill training because I've got Lakeland 50 to look forward to...
sevendaughters: "getting around" a marathon should be okay IF you've trained up to the mileage okay and you keep the speed down - look at what speed you've been doing 20+ mile training runs, then set off slower, and keep the fuel going in.
Fueling is the other thing that's trained differently on ultras. Start eating real food - malt loaf, fig rolls, currant buns, whatever - during your long runs, not just gels. I don't use gels at all, but I do use Kendal mint cake as well as the other things I mentioned.
