Sural nerve. The sural nerve is a sensory nerve in the calf region (sura) of the leg. It is made up of collateral branches of the tibial nerve and common fibular nerve. Two cutaneous branches, the medial and lateral, form the sural nerve.
1. Re: what's the best way to travel from Barcelona to Madrid ? Without any doubt, the train is the best way to travel between Madrid and Barcelona. It makes the 620 km (385 miles) that exist between both cities in 2 hours and a half, at speeds up to 300 km/h (186 mph).
Take a high-speed AVE train directly from Barcelona Sants station to Madrid Atocha. At peak times Barcelona to Madrid trains depart every 30 minutes, with the fastest services taking just 2 hrs 30 mins to reach the Spanish capital. Trains that stop up to four times along the way may take 30 to 40 minutes longer.
