sounds like you’re doing good. However, i would suggest instead of long walks (which were destroyed by your spanish sun anyway) do timed sprint sets. This helps to boost your metabolism moreso than really long distance excercises, which actually cause your body to adjust to your workouts and burn fat at a slower rate, at least I believe that happens. However I’m not a certified nutritionist, all I know is that after i cut out the long distance running and switched to sprint sets every other day with lifting in between, I started seeing results.

You might also want to vary you ab excercises a bit, leg raises are good, but just like the long distance running, your body may just adjust itself to the excercise. Throw in some crunches and plank stances.
