At your fitness level, you're more than capable of doing a long bikepacking trail.
The hard part isn't really fitness (for any moderately experienced biker unless your trip has a specific time or FKT goal), it's the logistics of food + shelter, the mental grind, and dealing with possible repairs.
Yeah I have done some trips before, max was 8 days with 85-100 miles each day, some decent elevation (max 11k feet in a day, but others around 5-6k) pretty bad weather, mix of paved and gravel. No chance I’m coming anywhere close to Lachlan’s time on GDMBR but I do need to finish in under 40 days.
This guy was using Rockbros bags and rack and I’m wondering if I should swap out my Tailfin for a more durable OMM rack…
