“I used Endurance every 45 minutes and rode very smoothly throughout – no bad spells at all – perhaps we should re-label Endurance as ‘Forever Young’.”
Charles Bruce, United Kingdom (Veteran 24 Hour Cycle Champion 1998 on missing his personal best time by 50 seconds, 27 years after setting it)
Endurance should be taken regularly throughout any activity to prevent cramp and fatigue. For intense exertion repeat more frequently. For longer events which are more endurance than aerobic, take one spray every hour. For activities such as hiking or backpacking, one dose every 2-3 hours is sufficient.
