Finish time statistics for timing chip holders:
Runners finishing between 59 min and 1:15 hr: 73 (4%)
Runners finishing between 1:15 hr and 1:30 hr: 116 (7%)
Runners finishing between 1:30 hr and 1:45 hr: 172 (10%)

50% of the runners finished between 1:45 and 2:30!
Since the above figures are for chip-holders only, I suspect they may include the more regular running populace, and hence the numbers may be biased a bit towards higher-performance (for example, most runners finishing in any given 15 minute slot may be in the 2:15 to 2:30 zone, but due to the timing-chip bias, is being displayed in the 2:00 to 2:15 zone).
