Let's calculate the miles Phillipa rode each day:

**Friday:**
\[
\text{Miles on Friday} = \frac{(13.5 + 8.5)}{2} = \frac{22}{2} = 11 \text{ miles}
\]

**Saturday:**
\[
\text{Miles on Saturday} = 18 - (2 \times 4) = 18 - 8 = 10 \text{ miles}
\]

**Sunday:**
\[
\text{Miles on Sunday} = 20 - (5 - 3) = 20 - 2 = 18 \text{ miles}
\]

Now, let’s summarize the miles ridden each day:
- Friday: 11 miles
- Saturday: 10 miles
- Sunday: 18 miles

Comparing the miles:
- Friday: 11 miles
- Saturday: 10 miles
- Sunday: 18 miles

The maximum distance ridden was on **Sunday**.

So, the answer is:
She rode her bicycle the most on **Sunday**.
