Nope, not on bike tours. I bring a big enough tent that I can get all my gear inside the tent. If it is raining in the morning, I can pack up my panniers when I am alone in my two person tent, so the tent is the last thing that needs to be packed.

Canoe or kayak trips where weight and bulk is less critical, I bring a tarp to sit under during those all day rains, and can cook under it on a stove in the rain. But do not bring on bike trips. The tarp I use for canoe trips is a Eno hammock tarp, but I do not have the hammock to use with it.

I used to bike tour with a single person tent, the last time it did that we had a lot of rain and I learned that I either needed a tarp OR a bigger tent, chose the bigger tent.

A local store has very thick plastic on some of their huge plastic bags, usually make tent ground sheets from that plastic for those times I have to set up a tent on gravel surface at a camp ground to protect the floor.
