Alright, San Diego, you want to know if today's a good day to push it? Not really, unless your idea of "pushing it" involves navigating closures and mud.
- Moderate Ozone is Still Ozone: While the air looks clear, that AQI of 62 with dominant ozone means it's not exactly crisp mountain air. If you've got sensitive lungs, you'll feel it, especially as things warm up later. Don't be a hero.
- Torrey Pines is a No-Go (Mostly): Look, I love Torrey Pines State Natural Reserve as much as the next sane runner, but the majority of those trails are still closed for upgrades, right through the end of February. So much for that scenic bluff run. They say full access is back by March 1st, but "upgrades" always run on "San Diego time."
- Recent Storm Lingers: Despite the current clear skies and pleasant 21.3°C, we just got hit with a few rounds of winter storms earlier this week. That means trails are likely still muddy, slippery, and possibly eroded, especially in canyon areas or anywhere prone to runoff. Don't be surprised by slick patches or unexpected standing water.

Your Workout, My Two Cents
The weather looks inviting, I'll give you that. Clear skies, a comfortable 21 degrees C – perfect for lulling you into a false sense of security. But don't let those pretty blue skies fool you entirely. While the pollen count is low (a win for us allergy sufferers, finally!), the AQI nudging into the moderate range due to ozone isn't ideal for peak performance. Think of it as running with a very subtle, uninvited companion sucking at your oxygen. If you're generally sensitive, or planning a truly brutal tempo run, you might want to adjust your intensity or stick to indoors.
Ozone Alert for Sensitive Individuals: That moderate AQI, driven by ozone, can irritate lungs, especially during strenuous activity. It’s not a full-blown smog alert, but if you have asthma or other respiratory issues, listen to your body and maybe dial it back or opt for earlier/later in the day when ozone tends to be lower.
Here's the real kicker for anyone eyeing a trail run: our beloved Torrey Pines State Natural Reserve is largely still off-limits. Most of the main park road, upper parking lots, and all trails within the main reserve have been closed for a significant upgrade project since last November, and that closure runs through the end of February. So, unless your workout plan involves dodging construction vehicles or getting cited by a ranger, forget about those iconic ocean views from the Razor Point Trail today. Your best bet is to stick to the South or North Beach parking lots if you just want to hit the sand, but don't expect to explore the bluffs. Full access is expected to return before March 1, 2026, so maybe next week we can talk.
And speaking of trails, don't forget we've had some significant rain lately. While the storms themselves might have passed, the ground is still saturated. This means mud, slippery sections, and potential erosion on unpaved trails. Areas near waterways, like those around Chollas Creek, might still be dealing with lingering wetness or ongoing flood mitigation projects that could affect access. Don't assume everything is dry just because the sun's out now.
Coastal Running Alternative: If your lungs can handle the moderate ozone and you're avoiding trails, stick to the boardwalks or paved coastal paths. Just be aware that high surf advisories have been in effect recently, so keep an eye on the waves if you're near the water's edge.
Honestly, today isn't terrible, but it's not without its irritations and limitations. Be smart, be safe, and maybe just embrace the treadmill today if your favorite trail is closed or too sloppy.
