How much slower is 10K pace than 5K pace?

Typical 10K pace is 6-10% slower than 5K pace. A 20-minute 5K runner (4:00/km) typically runs 10K at 4:14-4:25/km for a 42:20-44:10 finish.

What is a good 10K time?

Under 45 minutes (4:30/km) is competitive amateur. Under 40 minutes (4:00/km) is strong club runner. Under 35 minutes (3:30/km) is county/regional competitive level. Under 30 minutes is approaching national-standard racing.

Should I run 10K with even splits?

Slightly negative splits (start at goal pace or 2-3% slower, then negative split if feeling good) are generally optimal. Positive splits lead to blowups in the second 5K when the lactic acid accumulates.
