We had a great time running with Erick on the Colonial Run during our vacation to Lima. Such a great time, in fact, that we decided to do another run with him the next day to San Isidro and the Miraflores Cliffs! Erick did an awesome job of keeping a steady pace all the while explaining the different sights we were passing. We entered into several fascinating buildings we would've never noticed on our own, and the highlight was going up to the rooftop of a hotel to see the view of the city (and a peacock and turtle which were apparently residents of said hotel). Both runs were around 10k and at our pace which was perfect. Erick is extremely personable, fit, and knows his city well. I can't recommend this tour enough!
