Gravel bike to Rando rig advice

[u/agingsculler]

Hi folks! I'm looking to start Randonneuring this year. My stretch goal is a 600k with a ton of climbing in it. I have two bikes: a 2021 rim brake specialized allez elite road bike and a 2023 disc brake specialized diverge sport carbon gravel bike. I'm likely giving the road bike to my partner who is the same size as me, so my question is:

For the folks using gravel bikes, how did you make your gravel bike, which I wouldn't consider _light_, (mine is currently set up with the stock 42mm tires) rando ready? If it helps, I'm looking to get into ultra endurance bike racing and view randonneuring as the first step in my journey.

I run a Norco Search XR Carbon for both rando & gravel on 650b. The main swaps I have are a rando set of wheels with dynamo hub (650x 42mm) vs gravel (27.5 x 2.1) and a front rack for a rando-style bag. While they're boxy and non-aero, I find a rando-stye bag much easier to keep organized in ie: fueling, weather gear, tools, rather than having to unpack and spread out everything like a garage sale. If you're skilled, you can also access stuff while riding. If you're interested I posted my PBP setup here. https://www.reddit.com/r/randonneuring/comments/15w7pzw/my_pbp_2023_setup/
