A July date with seven-hour timing and expo collection
The homepage calls the course flat and fast, but its general description does not establish a detailed 2027 map or exact starting street. Check the new full-distance route and start instructions before setting a pacing plan or choosing accommodation solely around a presumed starting point.
The policy describes seven hours of timing, using both the marathon start and the final participant crossing as reference points in different sections. Treat that wording as something to resolve in the final guide. Check intermediate road reopening and support withdrawal as well as the finish deadline; chip time alone does not guarantee continued course access.
Bring the race confirmation number for expo bib collection and wear the assigned bib visibly on the front during the race. Transfers are handled case by case, so use the organizer’s process rather than exchanging a bib privately. Confirm the expo hours before booking an arrival that could miss collection.
The policy prohibits dogs and strollers in the marathon and half marathon and excludes unregistered participants, bikes and other unauthorized vehicles from the course. Supporters should remain outside race boundaries. Plan meetings and any permitted assistance around the official rules, rather than assuming a companion can cycle beside you. Check the final participant email again before leaving for the expo.
