"Even if, hypothetically, one could admit that Gerald and Kate McCann might be responsible over the child's death, it would still have to be explained how, where through, when, with what means, with the help of whom and where to they freed themselves of her body within the restricted time frame that would have been available to them to do so. Their daily routine, until the 3rd of May, had been circumscribed to the narrow borders of the 'Ocean Club' resort and to the beach that lies next to it, unknowing the surrounding terrain and, apart from the English friends that were with them on holiday there, they had no known friends or contacts in Portugal."
Matthew's rogatory says he and Kate had a long run outside Luz prior to 3 May. That appears to have been up Valverde (M537) to the junction with the N125 beside Boa Vista.
From memory, Kate was not asked where/when she ran, up to and including 3 May. She only notes running along the beach on 3 May when the T7 were at the Paraíso. The beach is 300m long, so at normal walking pace it takes 3 minutes to cover end to end. That seems somewhat short for Kate's capability, but the truth is we are missing information about her runs.
As to whether Gerry ran up to/including 3 May, we also seem to be missing information.
It doesn't take a car to get out of Luz. I have walked to Burgau and back a number of times. (My knees are no longer fit for jogging.) I have done it both by the M537 road and by the off-road costal path.
