I did the Lanhydrock 10K last year: yes, it is hilly! The thing is, there isn't just one, there are several. I gamely ran the first uphill section, jogged the next uphill bit, had just about recovered when a particularly horrid one came up at the halfway mark - I walked it! I just about managed the last uphill bit to the finish.
As other people have said, don't run them, power walk. Did a race last night (first since Lanhydrock!) and my friend and I overtook a few people who were bravely attempting to run a hill. My pace was actually better than Lanhyrock. So, don't exhaust yourself trying at this stage. Oh, and I am running at Lanhydrock again this year, so it can't be too bad.
