Frequently asked questions
What pace do I need for a sub-4 marathon?

What pace is a 3:30 marathon?

Should I run negative splits in a marathon?
Many coaches recommend running the second half equal to or slightly faster than the first. Start at or just below goal pace, and only push once you pass 30 km feeling in control.
