While Allopurinol is effective at controlling uric acid levels, physical exertion can temporarily increase uric acid production; this, along with the possibility of dehydration from riding in hot weather, may be creating the ideal storm for your symptoms. It's important to stay hydrated, especially when exercising. You may also want to talk to your doctor about modifying your dosage of Allopurinol or trying other preventive measures like dietary changes.

It's definitely worth exploring alternatives to the Ayamonte ferry, especially in winter months. Here's a quick breakdown:

Alcoutin: Ferry exists, unclear about bikes. Try contacting them directly at +351 281 540 170 or +351 926 682 605.

Pomarao: Smaller operation, RideWithGPS suggests it accepts bikes. Contact info might be harder to find, but local cycling forums or shops might have insight.

Alternatives: Consider a detour via El Granado dam or even crossing Spain further north (Merida?).

Tip: Winter may impact schedules, so contacting ferries/authorities beforehand is crucial.

Good luck navigating the river (and bureaucracy)!
