The trip is in three months, it's time to list down the gear I'll be needing and proceed to look for the best bargains.
Clothing - $0
I'll be packing lightly, not different from usual. 1 rain jacket, 1 merino sweater, 3 t-shirts, 3 underwear, 3 pairs of socks, 2 pairs of shorts, 1 pair of jogging pants.
Transport - $0
I already own a road bike that's good enough for Eurovelo roads, and all I'll be carrying fits in a 30L backpack. Additional bike bags would be overkill, so I'll just take bungee cords to strap the sleeping material to the saddle/handlebars and sew a small custom bag to the frame to carry some small groceries.
Work - $26 + <$10/month
Laptop, mouse, camera, tripod, lavalier microphone, smartphone, Kindle, mobile data (< $10/month, just need 1Gb as a safety measure if I can't post my 200 words or get lost), long battery life MP3 player to listen to music and audiobooks while biking ($26).
I'll be working from coffee shops, so I won't need anything else.
Housing - $101
Hammock with mosquito net and rain protection ($72), sleeping bag ($24), inflatable pillow ($5)
Msc - $16
Personal hygiene products (hard soap, nail clipper, toothbrush, earpick), headlamp ($16), opinel knife.
I'll also need a bike repair kit. I had some problems during my last tour, don't want to be unprepared this time.
Bonus: Food - ~$20
Portable wood burning stove: $18 + enamel pot
Grand total: $163
Except for that, most of my costs will come from food, coffee, and occasional Airbnb stays. The good thing is that most of my housing costs end up becoming long-term investments: the more I use them, the less I spend in rent.
