In March 2020, two friends and I walked from Sarria to SDC. Our plan was to walk to Finisterre then Muxia then back to SDC, but Covid intervened. We were all
70-ish years old with various ailments and arthritides of various joints, some replaced, sleep apnea needing a CPAP machine.
To maximize our chances for completion we traveled with packs under 10 kgs, used daypacks to carry rain gear, medications, blister treatment, CPAP, and food drink weighing about 5-6 kgs. We used a luggage transport service to send the rest of our belongings ahead.
Since a good, lower level (not upper bunk) bed is necessary for those with joint and spine issues, we reserved ahead of time at casas rurales, albergues, private apartments, and had a good experience. This worked well as many albergues, cafes, hostels were still not open.
On our first day, we walked 25 km to Portomarin and not a single albergue or other lodging was open until Portomarin, and the only place open was a small cafe within view of Portomarin.
To limit discomfort, we used Arnica gel(an herbal product), then applied Voltaren gel(NSAID gels were available in the pharmacies in Galicia), and we also used Salonpas(camphor, menthol patches). Since two of our three were on blood thinners for atrial fibrillation, we could not take NSAIDS by mouth.
Good beds made a huge difference.
In Palas de Rei, we used an apartment that had an excellent massage therapist on the ground level that we all utilized (Thanks, Marta!).
After the first day, we limited ourselves to walking 12-18 km, took breaks and sat every 1-2 hours, maintained hydration, and did not have any significant injuries.
Slow beats sore and painful.
Baggage transfer service was recommended by a priest that is our age and a relative of one of our group. Two of our three used it, and the third admitted that his back wished that he had also.
Our total expenditure for lodging and luggage transfer for 13 days in Spain was under 450 USD, about 350 Euros.
We are now discussing Camino Ingles or Camino Senda Literal.
Any other older folks with sleep apnea, mobility, joint, heart type issues that are willing to chime in and add comments on their experience?
Is anyone aware of a reference for known, knowledgeable, compassionate, medical providers on the various Caminos?
Good luck.
