ロードバイクで走行中の補給方法と補給が必要な理由について解説の動画です。

On the bike fuelling still appears to be somewhat of a myth to some riders. We know many cyclists that go out almost daily, yet never for more than 90 minutes, as their performance starts to drop. Here we give our guide to how and why you should fuel on the bike.

The reason they suffer after 90 minutes? They never actually eat on the bike! They take a bottle of water, but expect to have enough energy to fuel themselves on quite challenging terrain despite not topping up their fuel levels regularly!

1 Energy Reserves
The human body can typically store around 90 minutes of glycogen. Whilst this figure is slightly open to debate and does depend a little on the individual, it is a good starting point to reference your fuelling to. Despite knowing you have that much energy available, it’s not necessarily a good idea to expect to ride hard for 90 minutes without experiencing some lack of performance.

2 Top up your energy levels.
Depending on the individual, the body will rapidly deplete its glycogen stores from around 40- 60 minutes. From this point onwards you will want to keep topping up your tank to prevent any drop of intensity to your workout!

We recommend something small, and simple every 20 minutes. An energy gel, for example, is designed specifically for this. But you can be creative. Honey sandwiches? Banana? Homemade figue slice?
