First marathon territory. Finish strong.
Plan your sub-5 marathon (or sub-4:59) with first/second-half splits. This is the most common first-marathon target — even pacing or slight negative wins here.
For a 4:00:00 marathon with a -2% negative, run the first half in 2:01:13 and the second in 1:58:47.
