We made Pontedeume to Betanzos on June, 5th, 2016. It was a sunday. Like all sundays in Spain, the supermarkets are CLOSED! So, you have 2 options: eat always outside or buy food in the previous day and carry it on your backpack while travelling.
We choosed the second option, that represented around 3 to 4kg extra in our backpacks. So, my gf’s backbapack should now be with 6,5kg and mine with 9,5kg. It is too much, i know, but the only way to face a big problem: you don’t have so many STOPS along the way where you can “re-fuel”. Believe it! It won’t be easy to find a simple coffee shop. Supermarkets? Forget it! Only in Miño or Betanzos. But it was sunday. All of them would be closed. Then, we were carrying this: our morning food, our lunch, our afternoon food, our dinner and also the breakfast of the following day. CRAZY! But we did well the math and still had food. We choosed tuna, bread, fruit, cookies, and chocolate to carry as main food. Of course, we used eated fruit, but fruit is very heavy to carry. But healthy.
Remember. We did this Camino with sun and temperatures between 23ºc to 28ºC. So, it was hot.
