To set expectation I have put together some SUP Foil Downwind math:

Take your **AGE** and add the number of **Pounds** you are over your college weight (age 20) and this is how many **Downwind sessions** you will need to get comfortable downwinding (defined as on foil ~ 50% of the time).

If you are **AGE 50** and **20 Pounds over your college weight** expect **70 sessions** to get adept at downwinding.

Some additional factors:

- **Subtract 10 sessions** If you come from a PRONE Foiling background
- **Add 20++ sessions** if you have NO paddling experience
- **Subtract 10 sessions** If you can flat water paddle up
- **Divide by 2** if you are in a place with GREAT bumps, meaning the Gorge or current running against the wind with good short period chop
- **Divide by 3** if you are using a Foil Drive this will cut down on your paddle ups and increase time on foil
- **Add 20+++ sessions** if you are attempting to downwind in the ocean with Mixed Wind Chop and Ground Swell and cross chop

**Past performance is no guarantee of future returns.**

But what do I know? I am coming from a SUP foil background 7 years with 1,500+ sessions. \>50 years old, 15 lbs too heavy. We have a resident “Pro”, Kyle Pemberton, mid 30’s, graduate of the James Casey club that I am trying to tag along with who did the run below 2 days ago. Mavericks to Santa Cruz 55 miles, 30 knots of wind in 10 - 14 foot swell.

I can flat water paddle up and have been hammering the open ocean conditions but wondering if I am aging out. I figured I would share this ‘estimate’ to inform others to improve their efforts and/or to gain any other valuable feedback.
