I'm starting to think about doing my first Ultra this year, but going for a fairly "gentle" introduction (if that's possible). There's a 6 hour race in August that I'm quite tempted by. It's on a flat 2km loop (part gravel path and part asphalt). Some food & drink will be available at every passing of the start-line.
The idea raises a number of questions. Does training differ greatly to "regular" marathon training? How much longer should the weekend long-run be (if at all)? Are back-to-back long run days worth doing? When it comes to race day, how do you go about pacing? Is it start slow and then slow down?
Sorry for all the questions and sounding like a complete newbie, but I'm into unchartered territory here.
For the record: I've run 2 marathons and currently training for my third (Boston). Running about 55-70 miles a week. Long runs are currently at 20 miles and will build to around 22 before race day.
All tips & advice greatly accepted.
