An easy bike loop is if you ride over to Foothill Rd/Junipero Serra area from Menlo Park, then you can do the Portola/Alpine/Sand hill loop + an out & back on Canada Rd. The loop is about 10 mi + 16 mi for out & back on Canada Rd + if you ride over from MP and you should be around 30. If you want to climb, you can go up Old La Honda (3.75 mi climb - about 8%) from the loop and hit Skyline Rd, make a right at the top on Skyline & you can ride over to the store (3 mi) & make another right to descend 84 (4 mi) or keep going on Skyline then make a right & descend Kings Mtn. ... depends on how the weather is up on Skyline this weekend & how much climbing you want...
For running, you can either hit trails (dirt)... mostly flat... or with hills.. or a mix of flat paved trails + dirt, some options are:
* Run on the trails alongside Canada Rd -- can park near Canada/92 or even around Edgewood Rd
* Can run on paved trail at end of 92 -- think it's Sawyer... it's flat
* Can head over to Shoreline -- park at the entrance, then run on paved trail + hit mix of dirt/gravel trails (shoreline exit off 101)
* Huddart park -- trails + hills .. there is an organized trail run this weekend

Have fun!
