About the design
Some runners chase a PB. This one just wants someone to protect the data if it all goes wrong on the trail.
A weathered vintage badge captures a lone desert trail runner mid-stride, headband on, cutting down a dusty path between towering saguaro cacti and a sun-baked mesa. Retro striped sky colours and a distressed texture give it a proper worn-in, adventure-poster feel, with the bold tagline If I Flatline, Save My Splits printed beneath.
A brilliant gift for the dad, husband, or trail runner in your life who takes their splits far more seriously than their heart rate warnings. Great for Fathers Day, birthdays, Christmas, or crossing the line at their next ultra.
Who it is for
- Trail runners and desert hikers who love a bit of dark humour
- Fathers Day, birthday or Christmas running gifts
- Dads, husbands and running club mates who track every split
- Ultra runners, 5k joggers, and weekend trail regulars
- Anyone who has ever joked about dying mid-run for a new PB
