What to do on a sunday in leszno?

Hello
On the chance someone reading this forum knows the Leszno area - any suggestions as to where I can take a group of ten people. I am looking for ideas - I can organise a mini bus, take them out to lunch somewhere and then...........

Have already visited Wroclaw the day before....
Thanks

then take them to Ekstraliga speedway, Unia Leszno.

Does it run most Sunday's then...

depends on what these people expect and what they like...
leszno has beautiful baroque churches and has strong protestant traditions...
very interesting history and sighseeing, but most people dont like it;)

I could just take them sightseeing in the centre during the morning followed by lunch but I would still need something to do in the afternoon. I was there the other week, started off with a little breakfast in one of those tiny cafe's outside the station followed by a little sightseeing and then a big ice cream in the square, more sightseeing and then lunch but afterwards....
