不可思議的配速.

It's difficult to run negative split in a race because we are used to run faster in the beginning or think that there might be some time left if we begin at faster pace. The other reason is that we are excited with adrenaline in the beginning without knowing that we'll get tired easily at the second half.

Since I plan to run Taroko, I checked the course. Looks like the second half is downhill, so it will be possible to do "negative split".

The second half (1:02:35) is faster than the first one (1:03:07). This is called "negative split". The Korean runner who beat all the other Kenyan runners and won the 2001 Boston also ran as negative split. Most of us are "positive split" - exhausted at the second half. One of the strategy for running a marathon is "slow start". I think this is the way to do "negative split".
