There are still occasional patches of packed snow/ice so bring your poles. This is an enjoyable hike with beautiful lakes, wooded trails and even a snack/rest room break at a Starbucks. It is about an 7.8 mile hike with 358 feet of elevation gain around lakes and among the woodlands of Reston. We'll meet in front of the Starbucks at the South Lake Shopping Center at 8:45 am and hike through the Glade Stream Valley and then along Lake Audubon and Lake Thoreau. We hike at a pace of approximately 2.5 mph while moving. You must be experienced with hikes of this length and elevation gain. Dogs are welcome on this hike in accordance with the NVHC Dog Policy.

Join our weekly walking meetup to have fun, maintain a healthy lifestyle, meet new people, and enjoy the weather! We meet Saturdays at 10am, halfway between the Reston *Container Store* and *Not Your Average Joes* (by the metal benches), leaving no later than 10:05. Every week, rain or shine, we start by walking along the Green Trail to reach Lake Anne Community Center. Once there, we pause for water/bio (often staying a few minutes extra from April-November, due to the local Farmer's Market), and then we circle Lake Anne and head back to our starting point. It's roughly 3-4 miles and takes about an hour and a half. Afterwards, some members will often head to *Not Your Average Joes* or another local restaurant for a quick drink/meal before tackling the day. This event is open to all ages and fitness levels. Dogs are welcome, and we recommend dressing for the weather (umbrella, water, snow shoes, hat, etc.) since we'll walk rain or shine. Also, feel free to bring a friend! By signing up, you accept and assume all risks and responsibilities with this activity, and nobody will be held liable.
