Why pacing your marathon is harder than it looks
Most runners train for months… but on race day, it’s surprisingly hard to know if you’re actually on track for a PB. Here’s why:
You don’t run exactly 42.195 km.
Unless you’re an elite on the perfect racing line, you’ll run 42.5–44.5 km. Your watch thinks you’ve finished long before the real finish line.
GPS goes wrong at big city marathons.
Tall buildings, tunnels, crowds, and thousands of devices all fighting for signal. Your pace jumps around. Your distance drifts. Your watch struggles.
Your watch shows pace — not whether you’re on PB schedule.
“5:00/km” means nothing unless you know what split you should be hitting for your target time.
The only reliable things on race day are:
• The official distance markers
• The time on your watch
• And your target splits
PaceBand brings those three things together — so you always know if you’re ahead, behind, or right on track.
