A Pacer’s Reflections: Guiding Runners to Their Goal

On a marathon course, the runners who draw the most attention are often not the elite athletes racing for the win, but the ones carrying colorful balloon flags, running at a steady, even pace, and cheering on hundreds of fellow runners along the way — the Pacers. Once you’ve served as a pacer, your understanding of the marathon will never be the same.

What Is a Pacer

A marathon pacer is a special volunteer role recruited by race organizers, tasked with running the entire course at a precise pace so that runners with similar target times can follow along. Common pace groups include:

• Full marathon: 3:00, 3:15, 3:30, 3:45, 4:00, 4:15, 4:30, 5:00
• Half marathon: 1:45, 2:00, 2:15, 2:30

Pacers typically carry or wear a balloon or flag marked with the target time, making them easy for runners to spot at a glance.

How to Become a Pacer

Basic Requirements

1. A stable full-marathon finishing record: at least 3–4 completed full marathons with consistent finish times
2. A comfortable margin above the target pace: to pace a 4:00 group, your own personal best should be at least within 3:30
3. Strong communication skills: you’ll need to guide and encourage runners for the entire course, so clear expression matters
4. A strong sense of responsibility: runners are trusting you — you cannot give up easily or drift significantly off pace

Application Process

Taiwan’s major marathon events (Fubon Taipei, Wan Jin Shi, Taipei Marathon, etc.) typically recruit pacers after registration closes, posting the call for volunteers on the race’s official website or in running communities. Applicants are usually required to submit proof of their running results.

Pre-Race Preparation: Stricter Than for the Runners Themselves

Pace Calculations

A pacer must know the target pace inside and out. Take the 4:00 pace group as an example:

• Per-kilometer pace: 5:41
• 5 km split time: 28:24
• 10 km split time: 56:47
• 21.1 km time: 2:00:00
• 30 km time: 2:50:42

Before the race, I repeatedly practice running 5 km segments at this exact pace, so my body memorizes the rhythm and I don’t need to stare at my watch the entire time.

Mental Preparation

The biggest challenge of being a pacer is the psychological weight — hundreds of runners are entrusting their finishing goal to you, and that responsibility is not light. Solid mental preparation before the race is essential:

• Commit firmly to the mindset of “no giving up, no matter what”
• Prepare responses for various emergencies (what to do if someone cramps up, how to help a dropped runner catch back up)
• Know the course’s aid station locations and distance markers

The Pacer on Race Day

Controlling the Rhythm at the Start

At the start of the race, the atmosphere is electric, and many runners unconsciously speed up. The pacer’s first job is to “hit the brakes” — hold firmly to your pace and help the runners following you learn to control their excitement.

“You absolutely must hold back for the first 10 kilometers, or you won’t have the strength for the second half.” This is the first thing I say every time we set off.

Verbal Guidance Along the Way

A good pacer is not just a lead runner but a mental coach. Along the course, I like to use a few go-to phrases to encourage the runners following me:

• “The pace is perfect right now, keep it up.”
• “20 kilometers in — you’ve cleared the first big hurdle.”
• “The wall is coming up soon. That’s completely normal — just stay with me.”
• “The last 5 kilometers are where you prove it to yourself.”

Handling Runners Who Fall Behind

Not every runner following the pace group can hold on the entire way; some drop off after the 30 km mark. At this point, the pacer has to make a judgment call: wait, turn back to encourage them, or keep leading the runners still up front?

The general principle is: don’t turn back, but linger a few extra seconds at aid stations to give slightly trailing runners a chance to catch up. Meanwhile, encourage the runners ahead: “You’ve already run really well — hang in there.”

The Meaning of Crossing the Finish Line

When I cross the finish line together with the runners who followed me the whole way, and see the tears and smiles on their faces, it’s a feeling words simply can’t capture.

“Thank you for pacing me the whole way — I finally broke 4 hours!” That one sentence makes every time I’ve served as a pacer worth it.

Being a pacer is a form of giving, but what you receive in return is far greater than what you give — it’s the purest connection that running can offer between people.
