Context: I decided to pace myself from the start and resisted the temptation to attack any hills - it proved to be a good plan , and I reached the first feed station after 20miles feeling fresh . I was rather perplexed to discover that the goodies on offer were not free ( as was suggested in the literature ) . I checked my pocket for money ... none to be found . I had a quick drink and continued on , worrying about how long I could continue without sustenance .

Question: Why did the writer pace themselves from the start ?

0. None of the above choices .
1. Because they wanted to attack hills .
2. Because the goodies on offer were not free .
3. Because they did n't want to get exhausted before it was finished .
