Standard Chartered Singapore Marathon 2019 - 29 Nov - 1 Dec (Fri - Sun) in Local Races Posted Friday at 03:28 PM 10 hours ago, okw said: Energy gels do help if consumed appropriately. Few other things need to be in place during the race too. Hydration, pace strategy etc. Hate those chemical gels. Have successfully used oral electrolytes which is waaay cheaper than the gels. Have used Repalyte - got from Watson - at the time was 5 satchets for less than $2. Also have made my own when I can be bothered with honey and salt.
