[A hybrid approach to hypoplastic left heart syndrome].

– Stage 2. Triacastela-Sarria (440 m above sea level). We walked toward Samos for 18.6 kilometers, avoiding the first 4 kilometers that run parallel to the road because they required reaching the top of a peak at kilometer 4.7 and had difficult sections for the support vehicles. We felt that the next section, Sarria-Portomarín, was inappropriate, with too many parts unsuitable for vehicular traffic – Stage 3. Portomarín (350 m above sea level)-Palas de Rey (5650 m above sea level), 23 kilometers. This is very rough terrain with an initial climb toward the Gonzar road (540 m above sea level), followed by a flat section of 4 kilometers and 2 more climbs to reach 700 m above sea level and another downhill section, and another climb to cross the Ligonde mountain range (580 m above sea level). This orography can disrupt the discipline of the gait and cause angina crises – Stage 4. Palas de Rey-Melide (455 m above sea level), 15.7 kilometers, and 5th stage, Melide-Arzúa (390 m above sea level), 13.6 kilometers. These stages run over hills and valleys crossed by 6 rivers that empty into the Ulla, with a continuous up-and-down path that tires the climber, and results in safety problems. Some sections pose difficulties for vehicular traffic – Stage 6. Arzúa-Arca (305 m above sea level), 18 kilometers, and stage 7, Arca-Monte del Gozo (345 m above sea level), 15.7 kilometers, flat and with no problems
