A month after my trip to Barcelona, I travelled to Budapest to present another paper on HIP called “Securing the IP-based Internet of Things with HIP and DTLS” [1] at ACM WiSec’13. In this paper, we present a full-fledged security solution for commissioning and maintaining secure group communication in the IoT.

Still amped by my inaugural sightrunning half marathon in Barcelona, I couldn’t wait for the last session to end and go out explore this bustling city. So, when all was said and little was done, I quickly changed into my running shoes and took off down the streets from my Grand Budapest Hotel.

Total distance: 23.7 km
Max elevation: 223 m
Total climbing: 556 m

Where to run? The Danube* runs right through Budapest, separating the city into its two parts Buda and Pest. “Seeing a lot of water […] is probably an important thing for human beings”, as Murakami puts it, so I choose my course alongside the river banks. Also, rivers, lakes, and seas – basically any kind of water front – often come along with some sort of park, sidewalk, or promenade that provide fast and car-free running grounds, a great view included:

  • GellĂ©rthegy: Traversing Elisabeth Bridge from Pest to Buda, climb up the GellĂ©rthegy Hill and collect some vertical. Provides a unique view on Pest.
  • West river bank: Tons of impressively old and big buildings to be seen here, including the Budapest History Museum, the Royal Palace, and the Matthias Church.
  • Margaret Island: A completely car-free island in the Danube within Budapest city borders. Has a cozy tartan run-way that goes completely around. My big stepping-stone for crossing back over to Pest.
  • Hungarian Parliament Building: Located on the east river bank, this is probably the most photographed building in Budapest. Different wo the west bank, the east river bank presents a straining and packed city-run that really challenged me on the last 5 kms.

When to run? Budapest may well get to hot in summer. So go very early or very late to avoid, also to avoid traffic and exhaust gases that seem to stick on the river banks.

* The Danube river runs for 2850 km from Germany to the Black Sea through 10 different countries  – more than any river in the world.
