There are a few bike paths, but they will not get you far. However, most roads have a designated bike lane, which is sort of like a bike path.
This is the road from Del Mar to Torrey Pines....
Del Mar horse racing track, right next to Solana.
Just a quick stop on the bridge to take a photo.
This is the old dam at Lake Hodges. The water here is good - no problem. I usually take one bottle, and sometimes on a longer ride, I stop at one of the public parks to re-fill......
Jesmond Dene road - one of my favorites! Hardly any traffic on it because there is a highway close by, that all the cars take. An example of a small road that does not really have a bike lane.
Got a little reminder on today's ride to-and-from Oceanside as to why I do not have a bell on my bike: I probably spent about half the time elbow-steering (for lack of a better word - since I do not have TT bars). It seems unlikely that in that position, I could reach quickly enough for a bell - my main concern is being able to reach for the breaks in an emergency.
