Frequently Asked Questions
What fitness level is needed to target 1h30 on a half marathon?
You must be able to run 10k in under 43 minutes (4:18/km pace). On 5k you should do under 21 minutes. These performances show you have the speed for 1h30 on 21k. You also need a solid intense training base.
Why are VO2 max sessions so important for this distance?
A 1h30 half marathon forces you to work at 85%+ of your max HR, heavily stressing VO2 max. VO2 max sessions (90-93% max HR) improve aerobic capacity and let you maintain fast pace longer.
What's the strategic race plan for my half marathon?
First 5k should be 4:10-4:15/km (slightly slower). Then progressively build to your target 4:15/km. From 15k onward, if you feel good, maintain or slightly accelerate. Mental game is key for the final 5k.
