A Little Under a Month Until My First 5K: Your 3-Week Plan

Hello Dominique, I am a bit less than a month away from my first ever 5k. I started running a year and 80 pounds ago. I am a 45 year old male averaging about 5 days a week — short days 3–4 miles, long days 6–7 miles, with a max of 8.5 recently.

Can you please give me a good training schedule for the three weeks leading up to my 5K? I'd like to shoot for under 28 minutes.

Answer by Dom: Tom, eighty pounds in a year and you're already running 8.5-mile long runs — that is a remarkable thing to read. Sub-28 minutes for a 5k is absolutely within your reach given the base you've built. Here is a straightforward three-week plan, including paces, a proper taper, and a race-day strategy so you arrive at the start line ready to run well.

1. What sub-28 means in per-mile terms
2. Weeks 1 and 2 — sharpen without overdoing it
3. Race week — taper and race-day strategy

Your Pace Target and Why You Can Hit It

Sub-28 minutes for a 5k means running at 9:01 per mile — or just under 5:36 per kilometre. That is your number. Write it down.

You're already running long runs of 8.5 miles. The 5k is 3.1 miles — not even half your long run distance. The question isn't whether you can cover the distance. It's whether you can hold 9:01/mile for 3.1 miles on race day. The goal-pace session in the next two weeks will answer that question directly.

For context, your easy running pace might be somewhere around 10:00–10:30/mile — and that is exactly right. Easy days should feel easy. The tempo and goal-pace work is where you start teaching your legs what race pace feels like. Don't try to run your easy miles fast. That just tires you out without making you faster.

Weeks 1 and 2 — Build, Sharpen, Test

You don't need to add mileage. You need to sharpen what you already have. Keep running five days a week and structure the week like this:

• Long run (one per week): Keep this at your comfortable distance — 6 to 7 miles is ideal at this stage. Run it easy. There is no benefit to pushing a hard long run within three weeks of a race.
• Goal pace session (one per week): This is the most important session in your plan. Run 1 mile easy, then 1 mile at exactly 9:01/mile, then 1 mile easy, then 1 mile at 9:01/mile — 4 miles total. If you can hold 9:01 comfortably on both efforts, your sub-28 target is realistic. If it feels very hard, adjust your race goal to 28:30–29:00 so race day is a positive experience rather than a struggle.
• Interval session (one per week): Alternate 3 minutes easy with 2 minutes at a pace that feels brisk but controlled — not flat-out. Do this for 3 to 4 miles total. See the interval running page for more on why this type of session is so effective.
• Easy runs (two per week): 3 to 4 miles at genuinely easy pace — 10:00 to 10:30/mile. These are recovery days. Don't race them.

Never do two quality sessions (goal pace or intervals) on consecutive days. Your body needs that recovery time. Hard session, easy day, hard session — that is the rhythm.

Race Week Taper and Race-Day Strategy

In race week, cut your total mileage by roughly 40 to 50 percent. You want to arrive at the start line feeling light and fresh, not flat and stale. Here is how I'd structure it:

• Monday or Tuesday: One final sharp session — 6 repetitions of 90 seconds fast with 90 seconds easy jog between them. About 3 miles total. Do this early in the week so you have at least 4 days to recover before the race.
• Wednesday and Thursday: Easy jogs of 20 to 25 minutes. Enough to keep the legs ticking over without tiring them out.
• Friday: Rest or a very gentle 15-minute walk. Nothing more.
• Saturday (race day): 5 to 10 minutes of easy jogging as a warm-up before you get in the start corral. A few short accelerations (20 seconds at slightly faster than race pace) to wake the legs up. Then race.

For the race itself: don't sprint the opening half-mile. It feels easy at the start because of adrenaline — and that is exactly what catches most first-time 5k runners out. Start at goal pace (9:01/mile), settle in, and push the final kilometre. Finishing strong feels far better than hanging on for dear life over the last mile.

Eat your usual breakfast at least 90 minutes before the start. Nothing new on race morning. Trust what you already know works.

Tom, this is an exciting day to have in your diary. You've already done the hard part. The race is the reward. Let me know how it goes. :)

Kind regards,
Dom

Frequently Asked Questions

What pace per mile is sub-28 minutes for a 5k?

Sub-28 minutes works out to 9:01 per mile, or 5:36 per kilometre. If you can hold that pace comfortably in a goal-pace training session, you're ready for race day.

Should I walk during my first 5k if I need to?

Yes — walking for 30 to 60 seconds is far better than completely blowing up. In your first race, finishing strong matters more than running every step. If you do need to walk, start jogging again as soon as you feel recovered. Many runners finish their first 5k with a run-walk approach and are happy with the result.

Do I need to warm up before a 5k race?

A short warm-up makes a real difference. Five to 10 minutes of easy jogging, followed by a few 20-second strides (short accelerations) before you get in the start corral, means your legs feel ready from the gun. Without a warm-up, you end up spending the first kilometre of the race warming up instead — your legs feel heavy and your pacing is unsettled for longer than it needs to be.

What should I eat on the morning of my 5k race?

Eat whatever you normally have before a morning run — and eat it at least 90 minutes before the start. Race day is not the time to try anything new. Porridge, toast, or a banana all work well. Avoid anything heavy or high in fat. Stay hydrated but don't overdrink in the final hour.
