Trail Races

\*\*\*Note: We have temporarily moved off of the UMD Track and are meeting at Herbert Wells Ice Rink (Same location as Thursdays) for our speedwork. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- Join us for a structured speed workout! If you are new to running, just getting back into it, or checking out the club for the first time, this a great first workout to join. All paces and abilities welcome. A pre-determined workout will be announced at the beginning and participants can adjust the workout to meet their needs and level. Workouts are usually planned by time, rather than distance, which helps accommodate the wide variety of paces that we have and allows the group to stick together. Warm-up starts at 6:30pm. Children are welcome, if accompanied by a responsible adult. **Parking information:** Free parking is available; park nearest the trail (farthest from the ice rink)

Tuesday Night Women's+ Ride at Wakefield This is the women's+ night ride at Wakefield Park in Annandale, Virginia. Brought to you by MORE. **Sign the ride waiver here:** [https://x.gldn.io/e/Wc3cUSEpC1b](https://x.gldn.io/e/Wc3cUSEpC1b) Ride Leaders Simona, Kathy, and Jessica Location Wakefield Park, Annandale, VA Schedule Meet up at 6:30 in the last parking lot. Park in the last parking lot. After you turn into the parking lot, make an immediate right and park (across from the purple recycling bin). We meet there prior to the ride. All riders joining this ride will need to accept the standard MORE liability waiver form. **Wheels down at 6:45pm** Ride will be about 1 to 1.5 hours, depending on the group. The ride leader(s) will try to start as promptly as possible. Bring: Trail-ready mountain bike, helmet, tube, and water. Optional: Tools, gloves, snacks, and lights. We will need lights this time of year. Pace Casual to moderate pace depending on the group. This is a no-drop ride. (A drop is leaving someone behind who is slower than the group. We won't do that - but if you feel like you are not able to keep up, please let the ride leader know.) All riding abilities are welcome, but it is recommended riders have a few off-road rides under their belts first. Terrain Wakefield is generally considered easier to intermediate by most riders. There are a few small stream crossings and some log obstacles. Riders should use good judgment and dismount when in doubt. The ride will typically consist of a mix of single track, fire roads, and other trail sections in the park. Directions https://more-mtb.org/collections/virginia-trails/products/wakefield-park Weather To protect and maintain the trails, the ride will be canceled if weather conditions warrant. Information on closures will be posted here.

**Pre-registration is REQUIRED. RSVP here - [https://hubs.li/Q046VS--0](https://hubs.li/Q046VS--0)** **Speaker:** Michael Novack, Solutions Architect at AIceberg **Topic title:** "Trust What You Can Trace: Making Agentic AI Explainable, Secure, and Enterprise-Ready" As enterprises adopt increasingly powerful AI systems, one critical challenge remains: understanding how and why these systems make decisions. Many modern models - especially large language models - operate as opaque “black boxes,” making transparency, compliance, and trust difficult to achieve. *This webinar introduces the AI Explainability Scorecard, a practical framework for evaluating the transparency of AI systems based on criteria such as faithfulness, consistency, accessibility, and comprehensibility*. Attendees will learn how different model architectures - from K-Nearest Neighbors to neural networks and transformers - vary dramatically in explainability and risk. **The session will also explore real-world techniques for improving visibility into complex models, including surrogate monitoring approaches that map AI behavior to comparable examples.** These methods help organizations build observable, auditable AI systems without sacrificing performance or scalability. By the end of this session, attendees will understand how to move beyond black-box AI toward transparent, accountable, and secure AI deployment - a critical step for enterprises scaling agentic AI in high-stakes environments. You will learn: **\- Why Explainability Is the Foundation of Trustworthy AI** *Learn why transparency isn’t just a technical preference - it’s becoming a legal, ethical, and operational requirement for enterprise AI systems.* **\- The AI Explainability Scorecard Framework** *Understand the five key criteria - faithfulness, comprehensibility, consistency, accessibility, and optimization clarity - for evaluating how explainable an AI model truly is.* **\- How Different AI Models Compare in Transparency** *Discover why some models are inherently interpretable while others require advanced methods to understand their behavior.* **\- Practical Methods for Making Black\-Box AI Observable** *Explore modern techniques - including surrogate monitoring models - that help organizations understand and audit large language models at scale.* 🔗 Stay Connected * **Learn:** Free talks and trainings on the [Ai+ Training platform](https://aiplus.training/). * **Read:** The latest in AI research on the [ODSC Blog](https://opendatascience.com/). * **Chat:** Join the conversation in our [Slack Channel](https://www.google.com/search?q=https://odsc.com/slack). * **Community:** Review our [Code of Conduct](https://odsc.com/code-of-conduct/).

The picnic stop is at Meadowbrook Local Park, 12.5 miles into the ride. **Please charge your batteries. The ride is on asphalt and often flat but we will encounter some hills. As usual, non-assisted bikers are most welcome.** Bring snacks, lunch and plenty of water. Pump tires, check brakes and charge your battery. Consider packing a spare tire tube. Check weather and dress appropriately. As always, this is a self-guided event. **We recommend you download the Ride with GPS route.** [https://ridewithgps.com/routes/46073614](https://ridewithgps.com/routes/46073614) The group stops a few times for slower riders to catch up. The distance will be 18.4 miles or shorter any time you are fully satisfied with biking for the day. For the E-bike Lovers group to be successful, we need to grow our membership carefully.
