Most people get stuck on the “bicycling for a month” part.
Nevermind that it’s Southeast Asia in August: the subtropical heat and humidity will be…challenging. A friend from Da Lat warned that my sink laundry won’t dry overnight, so no doubt it will be waving like flags from the bike as I pedal along. Training/conditioning will mean going out for long rides in the mid-day DC heat.
But the bigger question remains, “How far are you cycling?” Here are projections based on the itineraries.
Total miles: 800
Average daily distance: 37 miles
Total elevation gain: 17,000 feet
Total days from Hanoi to Bangkok: 26
Days in the saddle: 21
Rest days: 5 (three of those traveling by boat)
Longest day: 60 miles
Which also happens to be the steepest day: 2,050 ft elevation gain
Shortest day: 10 miles (sightseeing in Hue)
This opportunity: priceless
The Journey in Between 
As far as sink laundry goes, when John and I backpacked Europe after my retirement, we invested in quick-dry items. We found socks and underwear that would dry in two-three hours and clothing that would dry overnight. Best investment we ever made. We still use them on our travels.
