review of 2017 Tunnel Vision Marathon.   

5 / 5 Stars


Being from south Louisiana the low temp and humidity (especially for August) was really nice. The shaded trail through the mountains was soooo nice.

Race Tips

Walk the tunnel the day before to get its feel. Even though it's 'trail' (not paved road) shoes with good cushion over the occasional larger gravel are a plus. Superb race.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

Parking, shuttling and spectating is a tad unique but well planned out. We stayed in Bellevue (about 30 min from buss pickup and finish). Plenty of hotel choices.

review of 2016 Tunnel Vision Marathon.   

5 / 5 Stars


Loved this race and this course. Beautiful and fast (my first BQ after 27 marathons). You would have a difficult time finding better August weather anywhere in the U.S. (it was 53 at the start and 66 when I finished).
