Here is 5.5 day pace. If I had kept going I would have ended up at Dicks Lake/Velmas at night so that’s why I stopped at Echo. Another half day and I would have been done in 5.5 so you need to be just ahead of these checkpoints basically.

My 4 camps were at Watson Lake, just past Mt Rose summit/Tahoe Meadows, close to Castle Rock near Kingsbury North, and finally Round Lake. Days 1 and 2 were a bit slow as I chafed and blistered early but rallied well for the rest of the trip. I set up a tent each day and wasn’t terribly efficient getting out of camp quickly so if you’re bivy camping you have some extra minutes on your side for sure.
The line on the east is Spooner. It would take ~2 days to get to Echo… almost a full day to get to Barker Pass from there. I would suggest you meet your family on highway 50 and that they have a super sized McDonald’s meal for you. A few quick photos, hugs and kisses, and be on your way. Hours of operation are 9-5 at the Chalet so it could be tough to thread the needle and get it right. Plus parking is a major issue unless she is there early, and there might be a line to wait in at the shop. Having a wife and kids myself… let’s just say that meal might take longer than it should given the pace you need to keep! There is a nice wide shoulder on 50 if I recall where they could park and wait for you. Check google maps street view to double check but I’m pretty sure it is like that because PCT thru-hikers wait there to hitchhike into South Lake.
Ideally you get to Lake Aloha (that would be 66 miles from Spooner) so you can get past Barker to finish Day 3. Maybe stop between the PCT/Ward Creek?
Then about a 1/4 of a day to get to Tahoe City, grab your food and jam as far as you can toward Relay Peak on that day 4. Last day you go for broke; up early and get at it. From Relay peak to Spooner summit it is ~30 miles and net downhill with good water at Galena Falls and Ophir Creek.
After my trip, and probably even during the 2nd half of it, I thought that the Spooner start would be most optimal for a fast effort. The toughest stretch I felt was from the far south point of the loop near Showers Lake all the way through Desolation so you get past that midway section and you’re really rolling from there. Keep us posted. You’ve obviously got me reminiscing, so thanks!
