Event Write-Up

By Göran Hellgren (LAOC), Event Director

A big thank you to all who helped out with Stage 2, and for the trust in me as event director. Thanks, Rex, for your support on everything from how BAOC operates to map printing and more. Thanks, Blake, for all your hard work on the courses and control setup. And huge thanks to Jay Hann and Sarah Williams — without you, things would have been way harder. You made it all run smoothly! I also want to give a big shout-out to all the volunteers who helped with setup, starts, control pickup, and everything else that needed doing.

Some reflections on how it all came together: After I agreed to take on the role as event director, we were told we couldn't hold the Sprint race in the Northstar Village. After a bunch of back-and-forth emails, we were eventually given access to the area northwest of the village — but with a condition: we had to avoid conflicts with mountain bikers. Amy Warren, Northstar's event manager, stepped in and helped us get everything sorted so we could go ahead with the event. Big thanks to her!

When Blake and I met up in early July, we realized the upper portion of the map hadn't been properly updated since 2006 (aside from a few sections). We spent two days doing some urgent map revisions, mainly focusing on trails and vegetation boundaries. After that, we worked out the courses.

After the final registration deadline, we saw that 79 people had signed up for the Long course, which would've made the forest pretty crowded. So we added a Middle-distance course, which turned out to be very popular, and helped spread folks out.

The day before the race, we set out the controls and SI units — not realizing it was going to snow overnight. (Cold weather is rough on batteries!) Three SI units died because of battery issues, but Blake was on standby at the Start, and fixed things pretty quickly once we found out.

Despite the snow, everyone finished their courses and seemed happy. Control pickup went smoothly. The next day, I went back out to collect some leftover flags and a forgotten sign.

Lessons learned:

  • Cold weather drains batteries fast — so think carefully about when to set out SI units.
  • If the route to the Start is complicated, hand out maps showing the way.

2025 Summer Series Results

The scores and standings after Event #4 in the BAOC Summer Series — Northstar at Tahoe — are below.

Before the scores, however, a huge thank you to Tahoe Event Coordinator Rex Winterbottom, Event Director Goran Hellgrun, and Course Setter Blake Tresan, and all the volunteers who made the eent at Northstar possible.

Also, a bit of explanation is needed. The Tahoe weekend attracted a large number of visitors from outside the Bay Area, which was fabulous to see, and their participation is truly appreciated. It has also led to a a slight deviation on how the Summer Series scores for this event were calculated. Clearly a lot of the visitors are not truly competing in the BAOC Summer Series — and will have competed in only the two Tahoe-based events of the Series. So, whereas technically they earned points in those events, including them in the scores could be problematic. This is because some of the visitors were clearly very competitive and recorded impressive finishing times. Including them in the scoring could have the effect of substantially reducing the scores of many other folks. (This is due to the handicapping system used to compute the scores as described elsewhere.) This in turn would "diminish" the impact of the two Tahoe events on the overall scoring (remembering that the Series is scored overall on each competitors best four events of the Series).

After careful consideration, it has been decided that this "diminishment" effect is undesirable, and not in the spirit of the Summer Series. Therefore, the competitors who will have taken part in only the two Tahoe events — and no other events of the Series — are not included in the scores and standings. And you will see they have been removed from the tables presented below.

This decision was taken in consultation with several other club members (and I appreciate their input), but I alone take full responsibility for the decision and the resulting adjustments. I know this was not announced in advance (I perhaps could have foreseen it, but I did not), so it feels a bit ad hoc. But I do think it is the right thing to do. If I have inadvertently removed anyone from the scores that should have been included, please let me know and I'll reprocess the results.

With all that said, the scores from Event #5 (Donner State Park on July 28) pose an additional twist. During the event one of the controls was moved by a member of the public, resulting in unfair conditions. Adjustments are currently being made in the interests of fairness, and hence it will take a little more time to process those scores.

Let me know if you have any questions, comments, or concerns about any of the above. And I look forward to seeing everyone at Event #6 at Evergreen Valley College on August 9th. See the event webpage for details.
