  Better than Sport

  • Leave Sport for PH 1500 when a more race-focused platform outweighs the source’s short training / long runs bias. PH 1500 centres on long runs / marathon. You give up Sport spec (type electrolyte-tablet).
  • PH 1500 advantage: high sodium dose for athletes who want electrolytes separate from carbs
  • Also stronger on: minimal carbs — won’t compete with PF 30 / gel math

  What you give up

  • You leave behind Sport's ultra-portable tubes for travel and race bags
  • PH 1500 downside: not a carbohydrate fuel
  • Only switch if not a primary carbohydrate source is a real problem — otherwise more race-focused is optional

  Who should switch

  Choose PH 1500 when long runs / marathon is the week and Sport is only winning on habit — not on more race-focused.

  Who should stay with Sport

  Stay with Sport if not a primary carbohydrate source is not biting; PH 1500's upside does not cancel not a carbohydrate fuel.

  Best for

  • Enough of what is built for without stretching it into another job.
  • Over a generalist when carb/electrolyte drink mix (1.5 g carbs/serving; no caffeine; 1500 sodium) is.
  • Pairs cleanly with Precision carb products.
