25 mile ride this morning from home to our south and back. Mix of suburban and rural roads. Several sets of fun rollers. Rode my ti long wheelbase 'bent, and spouse rode her Trek e-assist bike. Average today was 13.5mph, which is faster than our normal tandem rides on similar route, slower by 1-2 mph than my typical averages, and 2-3 mph faster than speeds on her Giant hybrid. She 's still learning to ride the new bike. Our goal is to ride together on single bikes regularly at speeds we both enjoy. Most of our riding together since about 2000 has been on a tandem. We are still riding a tandem but we are mixing it up with her new bike. She is able to catch up without difficulty after I blast down hills. Fun for both of us.
