This rig is mentioned in the above post.
Last Wed. I did a clockwise loop from El Dorado Park out to the SART, exit at Slater to Sea Point Dr., PCH, then SGRT north back to El Dorado.
Somewhere near Centennial Regional Park (Edinger cross street) I was passed by an enclosed, 3 wheel recumbent at high speed. I was doing about 15 MPH (southbound) up from the under-crossing, looked back, and here he came doing slightly under 25 MPH. I could see he was turning the pedals at maybe 100 RPM, and the rig was silent, so I presume no electric motors. I think its called a Velomobile because of the 3 wheels.
This is the yellow, banana, 3 wheel recumbent that seems to be from Netherlands. Not sure where he entered the trail, but I guess at the Centennial Park since I was watching the trail as far back as possible.
It was a good 40 mile ride overall. Highlights:
--puncture near Harbor Blvd. and Lampson from a thin wire
--plenty of Roadies on the SART, some going very fast, one with a Go-Pro
--no sign of the OCTA/Oc Parks Gauntlet
--rode with 3 strong, young guys on single-speeds from Anderson, across Huntington Harbor, into Seal Beach.
