I saw quite a few trikes, both tadpole and delta, during the 2007 Katy trail ride. They all seemed to be enjoying the trail. The trail was smooth that year with a few soft spots due to recent flooding.
The condition of the trail will depend a lot on the weather just prior to your ride. If it has rained hard, there may be washed out areas and ruts from other bikes and vehicles.
